You can put this solution on YOUR website! A father is 28yrs older than his daughter. in 2yrs time he will be 3 times as old as his daughter.find their present ages.
-------
f = d + 28
f+2 = 3(d+2)
----
Substitute for "f" and solve fr "d":
(d+28)+2 = 3d+2
d+30 = 3d+2
2d = 28
d = 14 yrs (daughter's age now
-------------------------------------
Solve for "f":
f = d+28
f = d+14 = 42 yrs (father's age now
