Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Match each equation with the correct solution.

Answer 1

5(x + 7) - 3(x - 4) = 7x + 2

5x + 35 - 3x + 12 = 7x + 2

2x + 47 = 7x + 2

5x = 45

x = 9

(1/3)(5x - 9) = 2((1/3)x + 6)

(5/3)x - 3 = (2/3)x + 12

x - 3 = 12

x = 15

4(3x + 5) - 3 = 9x - 7

12x + 20 - 3 = 9x - 7

12x + 17 = 9x - 7

3x = -24

x = -8
