You can put this solution on YOUR website!
x and y, bunty and son.
x-2=3%2A%28y-2%29, the first part.

The "two years hence" part:
2%28x%2B2%29=5%2A%28y%2B2%29, but this may be ambiguous in the wording.

Those then are two equations in the two unknown variables.

Simplifications will give:
x-2=3y-6
x-3y=-6%2B2
highlight%28x-3y=-4%29
and
2x%2B4=5y%2B10
2x-5y=10-4
highlight%282x-5y=6%29
-
Solve the system of the two equations.
