Question

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

Answer 1

Multiply the 3 throughout (x+1). Also multiply the -2 throughout (x-1)
3x+3 = -2x+2-4 (a negative times a negative makes a postive, making the 2 positive.)
3x+3 = -2x-2 (add 2x to both sides, to get rid of it on the right side)
5x+3 = -2 (subtract 3 from both sides, to get rid of the 3 on the left)
5x = -5 (divide 5 from both sides)
x = -1

Answer 2

3x+3 = -2x -2
3x + 3 +2x = -2x -2 +2x
5x+3 = -2
5x+3-3 = -2 -3
5x = -5
5x / 5 = -5 /5
x = -1
