7x1x108 solution equation? 7x ten 24 73 solution equation?

From the fifth grade of primary school, mathematics learning begins to learn simple equations, for simple equations, students will not feel very difficult, but for some complex equations, such as 7x-8 = 2x (4-x) = 9 (x-4), x 2 = (3x-10) 5 students are at a loss, do not know how to find a breakthrough to solve the problem, so that in the future study of practical problems, only the equation can be listed but not solved.

It is very important for students to learn complex equations because of some complex application problems, so in September, according to the experience in teaching, the teacher compiled the method of solving complex equations into a smooth way to help solve complex equations. Hurry up and look down.

Learn this mantra and never have to worry about not being able to solve equations again.

For example, 7x-8=2x+7, like this, there are equations with x on both sides, so that children can understand arithmetic on the basis of the child's joy, through the child's joyful crossing drama, let the x on the side of "=" cross to the other side, in the process of crossing, remember to change the sign. Combine a few example questions to experience what it's like to travel through.

Problem solving idea: 7x-108=6x-8

For example, when x=2, then 6x-8=6 2-8=12-8=4 improve: 1. Preview: Preview is not equal to browsing, to have an in-depth understanding of the knowledge content, find out the key points, difficulties, doubts, after thinking, mark out what you don't understand, which is beneficial to listening to the lecture and grasping the key points, and can also cultivate self-learning ability, and you can also learn ahead of time if you have time.

2. Listening: The core is in the classroom. 1. Listening-oriented, taking into account recording. 2. Pay attention to the process and ignore the conclusion. 3. Focused. 4. Improve the efficiency of lectures.

2. To do a math problem, you must ask more individual whys at every step, not just be satisfied with the indoctrination teaching in the teacher's classroom and the simple description in the book, if you want to improve, you must push step by step, think step by step, and every process is essential. 3. Don't be careless. 4. After completing each question, you have to think about why you think of doing this, the brain establishes a conditional launch, the key is to get something from each question, and what is wrong.

5. There are fixed routines for problem solving. 6. There is also a bold praise of yourself, which is a critical moment to build confidence, and 5. Summary. 1. It is necessary to turn the knowledge learned into a knowledge network, from the main trunk to the branches, clearly and deeply in the brain, and the new questions will be thought of the old ones, so as to make a fool of them.

2. Establish a set of errors, most of the mistakes will be wrong twice, in the case of conscious correction, there is still a possibility of mistakes, the most effective should be to do this question correctly, and the next time you encounter the same situation, you will have the awareness of attention. 3. At the end of the week, look back at the questions you did in the week and put forward the ideas and methods for each question. 4. If you have any questions, you must ask.

Excuse me: 1+7x=8 to solve the equation.

1) Move the term to obtain: 7x+3x=8-6, merge the same term, obtain: 10x=2, and the coefficient is reduced to 1:

x=1 5 ；2) Remove the denominator, get: 4x-2(2x+1)=36-(8-x), remove the parentheses, get: 4x-4x-4=36-8+x, move the term, merge the same kind of terms, get:

x = 32, the coefficient is reduced to 1 to obtain: x = -32

1+7x=8, move the term to get 7x=8-1, merge the same kind of term to get 7x=7, and the coefficient is 1 to get x=1So the answer is: x=1

This equation is incomplete, so there is no solution.

Unary Linear Equations.

General solution: denominator Multiply both sides of the equation by the least common multiple of each denominator.

Remove parentheses Generally, the parentheses are removed first, the middle parentheses are removed, and the curly braces are finally removed. However, the order can sometimes be made easier to calculate, depending on the situation. The property can be assigned according to multiplication.

Move terms Don't forget to change the sign when moving the term with unknowns in the equation to the other side of the equation, and moving the rest of the terms to the other side of the equation.

Merge Homogeneous Terminology Reduces the original equation to the form ax=b(a≠0).

Coefficientization1 The coefficients of the unknown number are divided by both sides of the equation at the same time to obtain the solution of the equation.

Binary Linear Equations.

General solution, elimination: the number of unknown numbers in the equation system is reduced from more to less, and solved one by one.

Unary quadratic equations.

There are four general solutions:

Formula method (direct leveling method).

Matching method. Cross multiplication.

Factorization.

This is an algebraic formula, not an equation equation, an equation with unknowns, and the result of this algebraic equation is 6x+8.

Solution: This is called factoring.

Original = 6x+8

Equal to 6x+8.

Dear, give it one.

It's not an equation, he doesn't have much.

Column equations. Calculate 7x+24=73

Problem solving ideas: In the process of solving equations, it is necessary to carry out the merging of similar terms including buried closure, and the unknown terms and constant terms.

They were merged separately, and finally the coefficient of the unknown terms was reduced to 1

Problem solving process: 7x+24=73

7x=73-24

x=49÷7

x=7 Extended Data Vertical Calculation - Calculate the Split Range: Align the subtraction with the subtracted digits, and then match them to the corresponding counting units.

The number on the subtraction, not enough to subtract need to borrow 1 from the high position, the result can be obtained by calculating in turn, the subtraction is less than the subtracted number, the two numbers will be exchanged and subtracted, and finally the fruit of the liquid pants will be added with a negative sign; The decimal part is subtracted by referring to the integer subtraction step;

Problem solving: Step 1: 13-4=9 Borrow 1 from the high position Step 2: 7-2-1=4

According to the above calculation steps, the combined calculation result is 49

If you have any doubts, please ask and be satisfied.

This problem solves the equation.

That's seven x = 8-1

Seven x = 7 x = 7 7

x=1Well, that's the step of solving the equation in this problem.

8-7 x=1

First of all, dig the object, so that both sides are subtracted from the eighth equation, and the branches are dismantled into a judgment of the liquid stand.

7x= 7 divides both sides by minus seven, and we get it. x=1

Solution: 8 7x=1

Solution: 7x=8-1

7x=7x=7÷7x=1

From the problem we get -7x=-7, then x=1. So x=1 is the answer.
