Answer 2

Answer:

5

Step-by-step 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)

$x = 5$
