You can put this solution on YOUR website!
Let J = Jaime's present age and S = his son's present age, then...
1) J+=+S%2B35 "Jaime is now 35 years older than his son."
2) J%2B5+=+2%28S%2B5%29 "In 5 years, he (Jaime) will be twice as old as his son."
Substitute equation 1) into equation 2) and solve for S.
%28S%2B35%29%2B5+=+2%28S%2B5%29
S%2B40+=+2S%2B10
40+=+S%2B10
highlight%28S+=+30%29 This is the son's age.
J+=+S%2B35
highlight%28J+=+65%29 This is Jaime's age.
