Question 473093
what number must be added to each term of 5/8 to yield 3/4
----
Solve: 
(5+x)/(8+x) = 3/4
Cross-multiply to get:
20 + 4x = 24 + 3x
x = 4
============================
what number must be subtracted to each term of 9/17 to yield 1/3
(9-x)/(17-x) = 1/3
----
27-3x = 17-x
---
2x = 10
x = 5
