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
