x 7 2 24 equation whole process?

Solve equations. (x+7)×2=24

Problem Solving Idea: Calculate a one-dimensional equation.

, first consider moving the term related to the unknown to the left of the equation, and then moving the constant to the right of the equation. If there are coefficients in front of the unknown, multiplication and division will be performed to get the final answer. So here, we can divide by 2 on both sides of the equation and then merge the same terms.

Put the unknowns to the left of the equation and the constants to the right of the equation to get the answer.

The detailed process of solving the equation is as follows, x+7) 2=24x+7=12

x=12-7

x=5So, you can get x=5 by the process of solving the equation above.

Extended information: Problem solving ideas: Generally, when we do calculations, the subtracted number is larger than the subtraction number.

If the subtraction is smaller than the subtraction, then a minus sign can be proposed to get the subtraction being greater than the subtraction. Then, when you do the subtraction operation, you should start the calculation from the low position. The corresponding number of digits, the subtracted number is less than the subtraction number, then it is necessary to borrow the digit from the higher digit to calculate.

Step 1: 12-7=5, borrow.

Step 2: 1-0-1=0

So, by subtraction of vertical calculations, the answer is 5

The first way to understand: the two sides of the equation are multiplied and divided by the same addition and subtraction of a number that is not zero, the equation still holds, and the steps to solve the problem are as follows:

Solution: Divide both sides of the equation by 3 at the same time to get :

x-7=8 is added to both sides of the equation at the same time to get :

x=15 The second way of understanding: according to the conventional thinking, the two sides of the equal sign are calculated first, and then the positions are exchanged according to the principle of position exchange of basic operations. The specific steps for answering the question are as follows:

Solution: Calculate first:

3x-21=24

Then, according to the principle that the subtracted minus the subtracted equal difference can be interchangeable to the subtracted equal to the subtracted plus difference, move the subtraction to the right of the equal sign to obtain:

3x=24+21

That is: 3x=45

Then according to the principle that the multiplier multiplied by the product of the multiplier equals the product can be replaced by the principle that the multiplier is equal to the product divided by another multiplier, move a multiplier to the right of the equal sign to get :

x=45/3

That is: x=15

Hello, this problem is a one-dimensional equation. The process of solving the problem is:

Divide both sides of the equation by 3 at the same time to get x-7=24 3=8, so x=8+7=15, and the solution of the equation is x=15.

Divide both sides of the equation by 3 to get.

x-7=8x=8+7=15

According to the question, the process of solving the equation in this problem is:

7x+x=24；8x=24；x=24÷8；x=3。

Hello, the result of x should be 3

Solution: 7x+x=24

7+1）x=24

8x=24x=3

After answering, I hope it can help you.

Untie ignition: (7+x) 2=24

7+x=24÷2

7+x=12

x=12-7

x=5 check: the left side of the equation is loose = (7+5) 2=12 2=24=the right side of the equation is dug out of the void, and the calculation is correct.

Hello! I'm glad to answer your questions!

Solution: (7+x) 2=24

7+x=24÷2

7+x=12

x=12－7

x=5 is your biggest support for me! Break a leg! Thank you!

Divide by 2 on both sides, 7+x equals 12, x equals 12-7=5

Solution: 7x 32 24

x 8 makes use of the property of the equation 1 look.

The result of solving the equation is that x is equal to eight.

Summary. 3(7+x) 2=24 equation. Hold on.
