Question

9x + 1 - 7x - 5 = -20

Answer 1

-8

Explanation:

First add together the x's.

2x + 1 - 5 = -20

Now add 1 and -5,

2x - 4 = -20

Add 4 to both sides,

2x - 4 + 4 = -20 + 4

2x = -16

Divide both sides by 2,

2x/2 = -16/2

x = -8

Answer 2

Aight so let’s simplify first: 2x - 4 = -20
Now let’s solve for x: 2x = -16, therefore x = -8
