Answer:

C choice.

Step-by-step explanation:

We can either solve the equation or substitute x = 4 to find the true equation.

Solve The Equations

1. 4x=20

Our solution would be x = 5 as we move 4 to divide 20.

2. x/2=8

Our solution would be x = 16 as we move 2 to multiply 8.

3. x+8=3x

Our solution would be x = 4 which is the answer. We basically move x to subtract 3x as we get 8 = 2x.

Then we move 2 to divide 8 as we get x = 4.

[tex]x + 8 = 3x \\ 8 = 3x - x \\ 8 = 2x \\ \frac{8}{2} = x \\ x = 4[/tex]

4.

[tex]x = \frac{x + 5}{2} \\ 2x = x + 5 \\ 2x - x = 5 \\ x = 5[/tex]

We simply multiply the whole equation by 2 to get rid of the denominator.
