  1. 1) 8х — 5 = х — 40
    7х = 35
    х = 5

    2) 9 + 13у= 35 +26у
    -13у = 26
    у = -2

    3) 6s+ (3s – 2) = 14
    9s = 16
    s = 16/94

    4) 8y – (7y – 142) = 51
    y = -91

    5) (6x + 1) – (3 – 2x) = 14
    8x = 14 — 1+ 3
    8x = 16
    x = 2

    6) (6 – 2c) + 4 = – 5c – 3
    -2c + 5c = -3 — 6 — 4
    3c = 13
    c = -12/3

    7) (10x–3) + (14x–4) = 8 – (15 – 22x)
    10x + 14x — 22x = 8 — 15 + 3 + 4
    2x = 0
    x = 0

    8) (7–10k) – (8–8k) + (10k + 6) = – 8
    -10k + 8k + 10K = -8 — 7 — 8 + 6
    8k = — 17
    k = — 17/8

    9) 6y – 20 = 2(5y – 10) – 4y
    6y — 10y + 4y = -20 + 20
    y = 0

    10) 6(1 + 5v) = 5(1 + 6v)
    5v — 6v = 5 — 6
    v = -1
