    -17 + b/8 = 13

    +17 + 17

    b/8 = 30

    x8 x8

    b = 240

    (-17 + 240/8 = 13 = - 17 + 30 = 13 = 13 = 13)

    7 (c - 12) = - 21

    7c - 84 = - 21

    +84 + 84

    7c = 63

    /7 / 7

    c = 9

    (7 (9-12) = - 21 = 63 - 84 = - 21 = - 21 = - 21)

    -3 + P/7 = - 5

    +3 + 3

    P/7 = - 2

    x7 x7

    P = - 14

    (-3 + - 14/7 = - 5 = - 3 + - 2 = - 5 = - 5 = - 5)

    46 = - 6t - 8

    +8 + 8

    54 = - 6t

    /-6 / - 6

    -9 = t

    (46 = - 6 (-9) - 8 = 46 = 54 - 8 = 46 = 46)
