    3b+2=6(3-b) becomes...

    3b+2=18-6b then...

    -2 -2

    3b=16-6b

    +6b 6b

    9b+16

    /9 /9

    b=16/9

    for the other one your equation becomes...

    3d-3+4= -2d

    3d+1= -2d

    -3d -3d

    1=-5d

    /-5 /-5

    d= -1/5 = -.2

    1. 3b + 2 = 6(3 - b)

    3b +2 = 18 - 6b

    3b = 16 - 6b

    9b = 16

    b = 16/9

    2. 3(d - 1) + 4 = -2d

    3d - 3 + 4 = -2d

    3d + 1 = -2d

    1 = -5d

    -1/5 = d
