Question 693151
Mr. Munch is twice as old as his daughter. In two years, he will be four times as old as his daughter was fifteen years ago. How old are they now?
-----
Equations:
m = 2d
m+2 = 4(d-15))
---
Substitute for "m" and solve for "d"
2d+2 = 4d-60
2d = 62
daughter = 31 yrs 
----
Solve for "m":
m = 2d
Mr. Munch = 2*31 = 62 yrs
