Answer 1

5

Explanation:

Use PEMDAS

First you should do is to combine like terms

`- x - 8 = - 13`

Haveing combined ike terms you need to add 8 to both sides (Like terms are terms that have the same variable like,x)

`- x = - 5`

Then divide by a negative 1

(this is to get rid of negative x)

`x = 5`
