Donnie’s height increased by 9 is 74 . Use the variable d to represent Donnie’s height.

Hey there!

“Increased by” means addition, so “Donnie’s height increased by 9” means Donnie’s height plus 9, so “d + 9”. And since it’s equal to 74, then “d + 9 = 74”. Therefore, your answer is “d + 9 = 74” (Or, it could be d = 74 – 9)
