A

Distribution Then Collect

1

Distribute, collect like terms, and solve for x.

1

2(3x−9)+20=3x+292(3x - 9) + 20 = 3x + 29

2

5(4x−6)+44=2x+325(4x - 6) + 44 = 2x + 32

3

3(2x−7)+25=3x+463(2x - 7) + 25 = 3x + 46

4

2(2x−5)+22=2x+382(2x - 5) + 22 = 2x + 38

5

2(3x−4)+21=2x+332(3x - 4) + 21 = 2x + 33

B

Variables on Both Sides

1

Collect like terms, move variable terms to one side, and solve for x.

1

6x+12−2x=2x+306x + 12 - 2x = 2x + 30

2

7x+4−2x=2x+167x + 4 - 2x = 2x + 16

3

8x+1−3x=3x+258x + 1 - 3x = 3x + 25

4

7x+11−2x=3x+217x + 11 - 2x = 3x + 21

5

7x+8−2x=2x+147x + 8 - 2x = 2x + 14
