a) x + 7 = 22 → x = 22 - 7 → x = 15

b) x + 15 = 51 → x = 51 - 15 → x = 36

c) x - 19 = 40 → x = 40 + 19 → x = 59

d) x - 25 = 50 → x = 50 + 25 → x = 75

e) 6x = 42 → x = 42 ÷ 6 → x = 7

f) 8x = 88 → x = 88 ÷ 8 → x = 11

g) x/3 = 9 → x = 9 × 3 → x = 27

h) x/8 = 7 → x = 8 × 7 → x = 56

i) 5x - 5=2x + 16 → 5x - 2x=16 + 5 → 3x=21 → x= 21 ÷ 3 → x = 7

j) 5x + 10= 2x + 40 → 5x - 2x=40 - 10 → 3x=30 → x= 30 ÷ 3 → x = 10

k) 4x - 3=3x + 2 → 4x - 3x= 2 + 3 → x = 5

l) 6x - 6=5x + 5 → 6x - 5x=5 + 6 → x = 11
