You can put this solution on YOUR website!
Give a variable to current age of each person, and LITERALLY WRITE THE EQUATIONS FOR THE DESCRIPTION. Solve the system of equations. Nothing strange.

Some of that:
e, Elaine
t, Tyler
-
system%28e=t-8%2Ce%2Bt=34%29

Do the rest!
Just a simple substitution is a good first step.
e%2Bt=34
%28t-8%29%2Bt=34
and continue...
