Question 834201
the running time for movie A is 31 minutes more than twice the running time for movie B. If the running time for movie A is subtracted from triple the running time for movie B, the result is 63 minutes. Find the running times for each movie
------
Equations:
A = 2B+31
3B-A = 63
-----
Substitute for "A" and solve for "B":
3B -(2B+31) = 63
3B - 2B - 31 = 63
-----
B = 94 minutes
---
A = 2B+31 = 2*94+31 = 219 minutes
