    a) 15 + x = 19
                 x = 19 − 15
                 x = 4
    b) x + 11 = 25
                 x = 25 − 11
                 x = 14
    c) x − 15 = 22
                 x = 22 + 15
                 x = 37
    d) 10 − x = 24
                 x = 10 − 24
                 x = −14

  2. a)
    15 + x = 19
    x = 19 – 15
    x = 4
    b) x + 11 = 25
    x = 25 – 11
    x = 14
    c) x – 15 = 22
    x = 22 + 15
    x = 37
    d) 10 – x = 24
    x = 10 – 24
    x = -14
