Question

Choose the equation that could be used to find two consecutive integers whose sum is 83.

n + (n + 2) = 83

n − (n + 1) = 83

n + (n + 1) = 83

n + n = 83

Answer 1

n+n+2=83

Answer 2

n + n+1 (this implies consecutive integers)
So 2n + 1 = 83
and then we can say that 2n = 82 (subtracting 1 from both sides)
So therefore n = 41, and as such n + 1 = 42
41 + 42 = 83 I think you will agree
