1) x + 5 = 10 2) 2x + 3 = 9 3) 32 ÷ x = 8
x = 10 - 5 2x = 9-3 x = 32 ÷ 8
x = 5 2x = 6 x = 4
x = 6 ÷ 2
x = 3
4) 9x + 10 = 28 5) x - 8 = 4 6) 6x = 12
9x = 28 - 10 x = 8 + 4 x = 12 ÷ 6
9x = 18 x = 12 x = 2
x = 18 ÷ 9
x = 2
7) x ÷ 13 = 130 8) x + 2 = 18 9) 5x = 75
x = 130 ÷ 13 x = 18 - 2 x = 75 ÷ 5
x = 10 x = 16 x = 15
10) 20 ÷ x = 4
x = 20 ÷ 4
x = 5
