Question

Solve for x: 3x-8=13. Show full work

Answer 1

`x = 7`

Explanation:

To solve for
`x` you need to isolate the
`x` terms to one side. We have to get rid of the negative 8. To get 0 from -8 we need to add 8. Anything you do to one side you do the other so:

`3x- 8 = 13` : Add 8 to both sides.

`3x = 21` : Now we have 3
`x` but we only want one. So divide both sides by 3.

`x = 7`

Answer 2

7

Explanation:

3x - 8 = 13

3x - 8 + 8 = 13 + 8

3x = 21

3x/3 = 21/3

x = 7
