What is the answer for - 7 = x/2 + 1

Begin by switching sides. That's an equal sign so there is no loss in doing that.

x/2 + 1 = - 7 Subtract 1 from both sides.

x/2 + 1 - 1 = - 7 - 1 When you subtract 1 from - 7 you get minus 8

x/2 = - 8 Multiply both sides by 2

x/2 * 2 = - 8 * 2

x = - 16

Answer: x = - 16

-7=x/2+1

Minus 1 on both sides

-8 = x/2

X=-16
