If 2x + y = 26 and x + 2y = 10, then (x + y)/3 =
Select the correct option
A) 1  B) 4/3  C) 17/5  D) 18/5  E) 4
We have two equations:   2x + y = 26   x + 2y = 10   Notice that something nice happens when we ADD them. We get:   3x + 3y = 36   Divide both sides by 3 to get:x + y = 12   So, (x + y)/3 =12/3=
