You can put this solution on YOUR website!
Let J be Jose's age today and s be his son's age today. You are told
J+=+s+%2B+27
%28J%2B10%29+=+2+%2A+%28s%2B10%29
J+%2B+10+=+2s+%2B+20
J+=+2s+%2B+10
Now you can substitute in the value for J in the first equation at the top into this last one
s+%2B+27+=+2s+%2B+10 now solve for s
27-10+=+2s+-+s
17+=+s so his son is 17 today
Which makes Jose 17+27 = 44
Check your answer based on what their ages will be in 10 years.
Is 54 = 2*27
