1) 12 + 8x = 44 ⇒ 8x = 44 - 12 ⇒ 8x = 32 ⇒ x = 4
2) 333 - 9 = 324 ÷ 6 = 54
3) n + (n+1) + (n+2) = 138 ⇒3n + 3 = 138 ⇒ 3n = 138 - 3 ⇒ 3n = 135 ⇒ n = 45
4) 150 - 12 = 138 ÷ 6 = 23
5) n + (n +2) + (n + 4) = 84 ⇒ 3n + 6 = 84 ⇒ 3n = 84 - 6 ⇒ 3n = 78 ⇒ n = 26
6) 45 ÷ 1/2 = 90 - 6 = 84
7) 14 - 6 = 8 ÷ 1/2 = 16
8) 11 - 9 = 2 ÷ 1/2 = 4
9) 3 + 7x = 31 ⇒ 7x = 31 - 3 ⇒ 7x = 28 ⇒ x = 4
10) (n+1) + (n + 3) + (n + 5) = 105 ⇒ 3n + 9 = 105 ⇒ 3n = 105 - 9 ⇒ 3n = 96 ⇒ n = 32 : (n + 1) = 32 + 1 = 33
