  1. a) x + 44 = 27
    <=> x = 27 – 44
    <=> x = – 17
    $\\$
    b) x – 22 = 12 + (- 4)
    <=> x – 22 = 12 – 4
    <=> x – 22 = 8
    <=> x = 8 + 22
    <=> x = 30
    $\\$
    c) x – 9 = (- 24)
    <=> x = – 24 + 9
    <=> x = – 15
    $\\$
    d) – x + 8 = (- 17)
    <=> -x = – 17 – 8
    <=> x = – 25
    <=> x = 25
    $\\$
    e) (- 19) – x = – 20
    <=> x = 19 – 20
    <=> x = – 1

  2. a, x + 44 = 27
    x = 27 – 44 = -17
    b, x – 22 = 12 + (-4) = -8
    x = -8 + 22 = 14
    c, x-9=(-24)
    x = -24 + 9 = -15
    d, – x + 8 = (-17)
    x = (-17) – 8 = -25
    e, (-19) – x = -20
    x = -19 – 20
    x = -39
