Let M = Maria's age
\n" ); document.write( "Let R = Orlando's age
\n" ); document.write( "Equation 1: $\"M+=+R+-+15\"$
\n" ); document.write( "Equation 2: $\"M+%2B+R+=+29\"$
\n" ); document.write( "-----------------------------
\n" ); document.write( "Note that equation one is solved for M.
\n" ); document.write( "Plug (R - 15) into equation 2 for M
\n" ); document.write( "Equation 2: $\"M+%2B+R+=+29\"$
\n" ); document.write( " $\"%28R+-+15%29+%2B+R+=+29\"$
\n" ); document.write( "Combine like terms
\n" ); document.write( " $\"2R+-+15+=+29\"$
\n" ); document.write( "Add 15 to both sides.
\n" ); document.write( " $\"2R+=+44\"$
\n" ); document.write( "Divide both sides by 2.
\n" ); document.write( " $\"highlight%28R+=+22%29\"$
\n" ); document.write( "Now plug 22 into equation 1 for R
\n" ); document.write( "Equation 1: $\"M+=+R+-+15\"$
\n" ); document.write( " $\"M+=+%2822%29+-+15\"$
\n" ); document.write( " $\"highlight_green%28M+=+7%29\"$ \n" ); document.write( "

\n" );
