Answer:

x = -7

Step-by-step explanation:

Original Equation:

-2(-2x + 3) - x - 1 = -28

Add 1 to both sides.

-2(-2x + 3) - x = -27

Use distributive property

-2 · (-2x) = 4x

-2 · 3 = -6

Your equation should look like this now:

4x - 6 - x = -27

Add 6 to both sides

4x - x = -21

Subtract x from 4x

3x = -21

Divide both sides by 3

x = -7

Hope this helped :)
