Solve the following inequality

4x < 248

• x > 62

• x = 62

• x < 62

Solve the following equation

• x = 3

• x = 11

• x = 28

• x = (-3)

How many answers can an equation have?

• Infinite

• One

• None

• As many as you want

r + 20 = 27

• r = 7

• r = 47

• r = 13

• r = 20

x-10=40

• 50

• 40

• 30

• 400

14 = x - 5

• -19
