1) 3x = 30 - 12 2) 5x = 35 + 20 3) 10x + 4x = 30 - 2
3x = 18 5x = 55 14x = 28
x = 18 / 3 x = 55 / 5 x = 28 / 14
x = 6 x = 11 x = 2
4) 2x = 26 - 10 5) 10x = 80 + 8 6) 5x = 40 - 18
2x = 16 10x = 88 5x = 22
x = 16 / 2 x = 88 / 10 x = 22 / 5
x = 8 x = 44 / 5
7) 2x = 9 - 3 8) 4x = 20 + 2
2x = 6 4x = 22
x = 6 / 2 x = 22 / 4
x = 3 x = 11 / 2
