I need to find the answer for

-3x + 7 = - x - 1

-3x+x=-1 - 7

-2x=-8

x=4

x = 4

Explanation:

-3x + 7 = - x - 1 Step 1: Add x to both sides

-3x + 7 + x = - x - 1 + x

-2x + 7 = - 1

Step 2: Subtract 7 from both sides

-2x + 7 - 7 = - 1 - 7

-2x = - 8

Step 3: Divide both sides by - 2

-2x / - 2 = - 8 / - 2

x = 4
