Question 828795
Ace Construction built five less than twice the number of houses that Ben's Construction built. If the total number of houses built by both firms was 115, how many did each build? 
-----------
Let Ben's Construct build "x" houses
Then Ace constructed 2x-5 houses
-----
Equation:
x + 2x-5 = 115
3x = 120
x = 40 (# of Ben's houses)
2x-5 = 75 (# of Ace houses)
