Question 335446
williams uncle is three times as old as william. in 12 years, williams uncle will be exactly twice his age. how old is william now?
------------
Equations:
U = 3W
----
(U+12)=2(W+12)
---
Substitute for U and solve for W:
(3W+12) = 2W+24
W = 12 yrs. (William's age now)
---------------------
Since U = 3W, U = 36 yrs (the uncle's age now)
