  1. b - 16.6 = -3.7.....add 16.6 to both sides
          b - 16.6 + 16.6 = -3.7 + 16.6
          b = -3.7 + 16.6
          b = 12.9

    14. 18.91 = -7.9 + x.....add 7.9 to both sides
          18.91 + 7.9 = -7.9 + 7.9 + x
          26.81 = x

    16. 295.8997 = -10.1k....divide both sides by -10.1
          295.8997 / -10.1 = (-10.1/-10.1)k
         - 29.297 = k

    18. -94.4724 = 3.3x....divide both sides by 3.3
          - 94.4724 / 3.3 = (3.3 / 3.3)x
          - 28.628 = x

    20. -29.4x = -148.764...divide both sides by -29.4
          (-29.4 / -29.4)x = - 148.764 / -29.4
          x = 5.06
