You can put this solution on YOUR website!
You can use substitution.
\n" ); document.write( "From eq. 2,
\n" ); document.write( " $\"-x%2B%281%2F3%29y=5\"$
\n" ); document.write( " $\"-3x%2By=15\"$
\n" ); document.write( " $\"y=3x%2B15\"$
\n" ); document.write( "Substitute into eq. 1,
\n" ); document.write( " $\"2x%2B3%283x%2B15%29=1\"$
\n" ); document.write( " $\"2x%2B9x%2B45=1\"$
\n" ); document.write( " $\"11x=-44\"$
\n" ); document.write( " $\"highlight%28x=-4%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"y=3%28-4%29%2B15\"$
\n" ); document.write( " $\"y=-12%2B15\"$
\n" ); document.write( " $\"highlight%28y=3%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
