Solve the equation:
4p = 16

• p = 12
• p = 64
• p = 3
• p = 4

Solve the equation:
x/3 = 4

• x = 12
• x = 1
• x = 16
• x = 3

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

Solve 2x - 3 = 1

• 3

• 2

• 1

• -2

Solve 3x - 7 = 32

• 13

• 3

• 12

-7x - 36 = 20 -3x

• -12
• -14
• 15
• 8

What is the value of 'x' if 3x + 2 = 2x - 8

• x = -10

• x = 10

• x = -2

• x = 2

Solve: 2x + 27 = 3x - 9

• x = 36

• x = -12

• x = -36

• x = 3

-5(3b + 12) = -3b - 5(b + 12)
