Multiple Choice

Solve the equation

حل المعادلة

8 + 6x = 26

• x = -3

• x = 2

• x = 3

• x = 5

Multiple Choice

Solve the equation

حل المعادلة

10 + 7x = 45

• x = 5

• x = 10

• x = 7

• x = 9

Multiple Choice

Solve: $$\frac{x+5}{2}=8$$  

حل المعادلة

Note: In THIS case, multiply by 2 FIRST on each side. You cannot subtract 5 first because that fraction is really $$\frac{x}{2}+\frac{5}{2}$$  

• x = -2

• x = 11

• x = 22

• x = 4

Multiple Choice
