  1. a, 3268 – x .2 = 2032
                   x.2 = 3268 – 2032
                   x.2 = 1236
                   x    = 1236 ÷ 2
                   x    =  618
    b, 4106 – x : 2 = 1002
                   x : 2 = 4106 – 1002
                   x : 2 = 3104
                   x      = 3104 × 2
                   x      = 6208
