A

1

4x + 7 - 2x + 3 = 24

x = 7

2

3(2x - 5) = 27

x = 7

3

-2(4k + 1) + 5k = 13

x = -5

4

5(y + 2) - 3y = 22

y = 6

B

1

7x - 4 = 3x + 16

x = 5

2

2(3n + 4) = 4n - 6

n = -7

3

9 - 2m = 5m - 12

m = 3

4

4(p - 3) = 2(p + 5)

p = 11

C

1

-3(2x - 4) + 8 = 4(x - 5)

x = 4

2

1/2(4x + 8) = 3x - 6

x = 10

3

5x - (2x + 6) = 21

x = 9

4

(3x + 9)/4 = x - 1

x = 13
