Translate the following situation into an equation. Do not solve.

“The sum of three consecutive odd integers is 85 less than four times the first. What is the first integer?”

anonymous · Answer

Let n = first integer
n + 1 = second integer
n + 2 = third integer

n + (n + 1) + (n + 2) = 4n - 85

3n + 3 = 4n - 85
88 = n
