Question

Choose the equation that could be used to find two consecutive integers whose sum is 67.

n + (n + 2) = 67

n − (n + 1) = 67

n + n = 67

n + (n + 1) = 67

Answer 1

The last one. The others could easily be eliminated since they give no consecutive integers. Just the second one might trick you, but you would have a difference then.

The last one it is, and the numbers are 33 and 34

Answer 2

Anyhow, you could also solve for "n" , getting 33, then add one and getting the second number. :)
