Question 180151
 I would like to know how to solve this problem. I don't want the answer, just the steps I need to use. 
Stephan cuts a 20-yard ribbon. One piece is 3-yards longer than the other. What is the length of each rope?
--------------
One length is s yards, the other is s+3 yards.
s + (s+3) = 20
2s+3 = 20
2s = 17
s = 8.5 yards
s+3 = 11.5 yards
