Solution: x=8Solve the equation:Solving an equation is the process of finding the values of all the unknowns in the equation. An equation must be an equation, and an equation does not have to be an equation. An equation without unknowns is not an equation.
After solving the equation in general, it needs to be verified. Verification is to substitute the value of the solved unknown into the original equation to see if both sides of the equation are equal. If it is equal, then the value obtained is the solution of the equation.

Solution: (52x=416.)
x=416÷52
x=8The relationship between equations and equationsAn equation must be an equation, but an equation is not necessarily an equation.
Example: a+b=13 conforms to the equation with unknowns. This is an equation and an equation.
1+1=2,100×100=10000。These two equations fit the equation, but there are no unknowns, so neither is an equation.
In the definition, the equation must be an equation, but the equation can have others, such as 1+1=2, 100 100=10000 as mentioned above, all of which are equations, and obviously the range of equations is a little larger.

Solution:
x=8 solution equation basis.
1. Shift the term and change the sign: move some terms in the equation from one side of the equation to the other side with the previous symbols, and add and subtract, subtract and add, multiply and divide, and divide by multiplication.
2. The basic properties of the equation:
1) Add (or subtract) the same number or the same algebraic formula on both sides of the equation at the same time.
The result is still the equation. It is expressed in letters as: if a=b, c is a number or an algebraic formula.
2) If both sides of the equation are multiplied or divided by the same non-0 number, the result is still the equation. The liquid return is represented by letters: if a=b, c is a number or an algebraic formula (not 0).

Summary. The result is equal to 8.
of the solution equation. The result is equal to 8.
Is it possible to write the process? I'm in fifth grade. ,x=,x=8
When solving the unary equation, the specific steps include: 1. Go to the denominator of the travel allocation 2, remove the parentheses 3 if you rent the town, move the term 4, merge the same term 5, and reduce the unknown coefficient to 1
Why 5x=
Is this a 5th grade process for you?
Yes. I'm a fifth-grade math teacher.
Thank you. <>

x=x=8 I don't know how to ask and lead, there is a help from Jingpai, thank you Liangpengxian!
Let me explain them one by one.
What is Equation? An equation with unknowns is called an equation. >>>More
The controversy converts the ratio in the proportion into a fraction and then solves the equation. >>>More
1. The equation is 2x+y=54, (2x)*y=144, so 2x, y are the two real roots of the equation x 2-54x+144=0, and the root formula can be obtained x1=27-3 65, x2=27+3 65, so x=(27-3 65) 2, y=27+3 65 or x=(27+3 65) 2, y=27-3 65. >>>More
Answer: The elimination method is to convert the duality into a unitary method, which is generally the addition and subtraction elimination method or the substitution elimination method. j
You should ask the first question, this does not need to solve the specific value, solve the expression form of cn about an, the ratio is a fixed value to prove it, <>
