x=10

Answer 2

x = 10

Explanation:

`2x-7=13`

First, add 7 to both sides.

`2x-7 + 7=13 + 7`

This cancels the -7 on the left side because
`-7 + 7 = 0`.

`2x=20`

Then, we can divide both sides by 2 to isolate one multiple of x.

`2x=20\\\overline{\ 2\ } \ \ \ \ \overline{\, 2 \: }`

`\boxed{x = 10}`
