Solve for x:

18 = x - 9

You must use: x=

Solve for x:

x - 15 = 18

You must use: x=

Solve for x:

34 = 16 + x

You must use: x=

Summarize how you solve the equation below.

50 = 12 + x

• Subtract 12 from both sides of the equation. (take 12 from the 12 +x side and take 12 away from 50)

• Subtract 12 from the right side of the equation. (just take 12 away from the 12 + x side)

• Subtract 50 from both sides of the equation. (take 50 away from the 12 +x side and 50 away from 50)

• Combine 50 and 12

Solve the equation.
46 = n + 19

• n = 37

• n = 27

• n = 65

• n = 30

x + 9 = 12

• x = 21

• x = 3

• x = -20

• x = 12
