For question 4.a), I think you meant x + 3 = 12.

4.a) x + 3 = 12

         - 3    -3

           x = 9

b.) 2x + 3 = 20

         - 3     -3

    2x = 17

     2     2

            x = 8.5

c.) -4x = -24

     -4      -4

    x = 6

d.) 2(x-4) = 10

    2x - 4 = 10

         + 4   +4

    2x = 14

     2     2

      x = 7

e.) -0.5x + 1.1 = -3.9

              - 1.1    -1.1

    -0.5x = -5

    -0.5     -0.5

         x = 10
