You can put this solution on YOUR website!
f and s, current ages for Father and Son

twelve years later u will be as old as I was 12 years ago...
s%2B12=f-12


...,& I shall be three times as old as you were 12 years ago"
f%2B12=3%28s-12%29


Think through those description parts and the equations which conform to them.


The system of equations summarized is system%28s%2B12=f-12%2Cf%2B12=3%28s-12%29%29.
Simplify and solve.


system%28f-s=24%2Cf%2B12=3s-36%29

system%28f-3s=-48%2Cf-s=24%29
Try E2-E1 to eliminate f.

f-s-%28f-3s%29=24%2B48
2s=72
highlight%28s=36%29


Find now, f.
f-s=24
f=24%2Bs
f=24%2B36
highlight%28f=60%29
