Which equation best first the following situation?

Some surfers recommend that a beginner's surfboard be 14 inches greater than the surfer's height. If a surfboard is 82 inches, how tall should the surfer be to ride it?

• 96 inches

• 68 inches

• h - 14 = 82

• h + 14 = 82

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

t - 1.9= 15.7

• t= 12

• t= 13.8

• t= 17.6

• 15
