Question

Solve for x: 3(x + 1) = -2(x - 1) - 4

Answer 1

3(x+1)=-2(x-1)-4
3x+3=-2x+2-4
3x+3=-2x-2
3x+2x=-2-3
5x=-5
x=-1

Answer 2

you can also check your work by subbing in the answer you got..
3(-1 + 1) = -2(-1-1) - 4
3(0) = -2(-2) - 4
0 = -4-4
0 = 0 (correct)

x = -1

Answer 3

3x+3=-2x+2-4=5x=2-7=5x=-5 therefore x=-1
