    Answer:

    Use the distributive property to multiply 3 by x+1

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

    Use the distributive property to multiply-2 by x-1

    3x+3=-2x-2

    Add 2x to both sides

    3x+3+2x=-2

    Combine 3x and 2x

    5x+3=-2

    Subtract 3 from both sides

    5x=-2-3

    Subtract 3 from -2

    5x=-5

    Divide both sides by 5

    x=-5/5

    Divide -5 by 5

    x=-1
