How to check two x 0 4 x 4 8?

2x+x=

x=2 so we can get it by the following process of solving the equation, and the x=2 test process is as follows.

Solve the equation: 2x+

x=2 test: substitute x=2 into the original equation, left = 2 * 2 + right. So, x=2 is the root of the original equation.

First calculate how much x is equal to this equation, and then test it. Take 2 x + x=, that is, divide both sides of the equation by x=, you can get x=, so the solution of the equation x=2, and then put x=2, left =2 2 + right. So the solution of the equation x=2 is correct.

Calculate the value of x first, and then bring the value of x to the equation, if the number calculated on the left is equal to the right, then the equation is true, and the value is correct.

First of all, calculate that it is equal to, x, and equal to two, and then bring two into the equation to see if two x + 0 points 4x are equal.

You need to merge the same kind of items first, so.

Point eight, and then divide both sides at the same time.

X=2 check is obtained.

It is to put two into the equation.

2 2 + 0 points 4 2 = 4 points eight, so the result is 24 = 2

Solve the unary equation, the obtained unknowns, into the equation, if the equation is equal, it means that the solution is correct!

Hello. Solution: 2x+

x=x=2 so we can get it by the following process of solving the equation, and the x=2 test process is as follows.

2 + check, put 2 generations in: 2 2 +

So =2

The solution is as follows. 2 x+ x=

x=x=x=2 This is the detailed process of solving this equation.

2x+ equals the test, calculate x first, and then substitute the result into the formula.

2x+2x=6x=3

Check: 2x3+, correct.

Solve the equation and write out the calculation process:1. Substitute the value of the unknown number into the original equation.

2. How much is the left side equal to, and whether it is equal to the right side.

3. Determine whether the value of the unknown number is the solution of the equation.

For example: solution: x=23

x=5 test:

Substituting =5 into the equation yields:

Left = 23 = Right.

So, x=5 is the solution of the original equation.

The coefficient is one: x=6

Get: x=25

The test brings x=25 in to see if it's =

The test is to substitute the result of x into the equation and see if it is equal to it.

x=x=2 brings Min to guess x=2 into the bridge.

Solution: x=12

Process: x=12 test:

Calculation method: 1. When there are unknowns in the question, put the unknowns in one place for calculation.

2. The x in the question is a one-time term, and the number 1 can be extracted and subtracted from the already known one, so that the unknown god pure forest number can be merged into a wandering mu formula.

3. According to the calculation rules, extract the same number on both sides of the equal sign to solve the unknown.

4. When checking, substituting the unknown number into the original formula can determine whether the calculation process is correct.

How to check?

The solution equation is as follows: the great void.

Solution: x=x leak mimicry test:

x=4 test: Equation Xiangfan buried on the left =

Equation car right =

So: x=4 is the solution of the equation.

Solve the unary equation, merge the shifts with similar terms, and turn the coefficients into one.

2＝8x＋。

2－8x＝。

3. Move the positive 8x to the left side of the equation and turn it into negative 8x, and the result remains unchanged on both sides of the equation.

x－x＝。5. Move the positive to the left side of the equation to accompany the negative equation to change the left and right sides of the equation, and the result remains the same.

x＝。7. Becoming 7x is equal to finding x, which is equivalent to 7/7 of x, dividing x.

8. The correct answer is x.

x ten ruined macro suspicions.

Solution: x=x=I hope to help you with your hand!
