the sum of the ages of Mr X and Mr Y is 48.
8 years from now Mr Y will be 3 times Mr X's age.
Find their present ages.
----
Equations:
x + y = 48
(y+8) = 3(x+8)
----
Substitute for y and solve for "x":
(x + 48-x) = 3x+24
3x = 48-24
3x = 24
x = 8 (Mr. X's age now)
----
Since x+y = 48, Mr Y is 40 yrs old
