Let M = Maria's age
Let R = Orlando's age
Equation 1: M+=+R+-+15
Equation 2: M+%2B+R+=+29
-----------------------------
Note that equation one is solved for M.
Plug (R - 15) into equation 2 for M
Equation 2: M+%2B+R+=+29
%28R+-+15%29+%2B+R+=+29
Combine like terms
2R+-+15+=+29
Add 15 to both sides.
2R+=+44
Divide both sides by 2.

Now plug 22 into equation 1 for R
Equation 1: M+=+R+-+15
M+=+%2822%29+-+15
