    8 (x + 1) - 3 (x + 4) = 7 (-x + 2)

    8 (x) + 8 (1) - 3 (x) - 3 (4) = 7 (-x) + 7 (2)

    8x + 8 - 3x - 12 = - 7x + 14

    8x - 3x + 8 - 12 = - 7x + 14

    5x - 4 = - 7x + 14

    + 7x + 7x

    12x - 4 = 14

    + 4 + 4

    12x = 16

    12 12

    x = 1¹/₃

    7 (x + 2) = 6 (x + 5)

    7 (x) + 7 (2) = 6 (x) + 6 (5)

    7x + 14 = 6x + 30

    - 6x - 6x

    x + 14 = 30

    - 14 - 14

    x = 16
