Mr.Edwards is now three times as old as his daughter, in 15 years' time the sum of their ages will be 86.
a.)How old are they both now?
b.)How old was Mr.Edwards when his daughter was born?
Write and solve an algebraic equation or inequality for this problem.

Let E=age of Mr. Edwards.
(E+15 + E/3+15) = 86
Solve for E.
