Add the equations together,
\n" ); document.write( " $\"x%2By%2Bx-y=4%2B5\"$
\n" ); document.write( " $\"2x=9\"$
\n" ); document.write( " $\"x=9%2F2\"$
\n" ); document.write( "Now use either equation to solve for $\"y\"$
\n" ); document.write( " $\"x%2By=4\"$
\n" ); document.write( " $\"9%2F2%2By=4\"$
\n" ); document.write( " $\"y=-1%2F2\"$
\n" ); document.write( " \n" ); document.write( "
