Question

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

Match the expressions with their equivalent simplified forms.
Tiles
10x + 6
2x − 8
3x − 5
2x + 14
2x + 6
10x + 14

Pairs
(-2x + 4) + 2(2x + 1)

2(3x + 5) − 4(x − 1)

2(x − 7) + (8x + 20)

Answer 1

(-2x+4)+2(2x+1) = 2x+6

2(3x+5)-4(x-1) = 2x+6

2(x-7)+(8x+20) = 10x+6

They should be the answers if the simplified forms can be used twice.

Hope that helped!

Answer 2

(-2x + 4) + 2(2x + 1)

2x+6

2(3x + 5) − 4(x − 1)

2x+14

2(x − 7) + (8x + 20)

10x+6
