Answer:

1. 5

2. 12

3. 6

4. 2/3

5. 5

Step-by-step explanation:

1. 5x + 8 = 33

5x = 33 - 8

5x = 25

X = 5

2. 2(x+10) = 44

x + 10 = 44/2

x+10 = 22

x = 22 - 10

x = 12

3. 5x - 14 = 16

5x = 16 + 14

5x = 30

x = 6

4. 7 - 4x = 2x + 3

7 - 3 - 4x = 2x

4 = 2x + 4x

4= 6x

4/6 = x

2/3 = x

5. 3x + 2x = 3x + 10

5x - 3x = 10

2x = 10

x = 5
