Question

12. What is the solution to 4x - 8 = 20?*
X = 6
x= 5
x=7
x = 8

Answer 1

`x=7`

Explanation:

First, add like terms. In this case, you would add
`8` to both side to get rid of it from the left side, and with its like term,
`20`.

`4x-8=20→4x=28`

Then, divide both side by 4 to isolate
`x`.

`4x=28→x=7`

The answer is
`x=7`.
