Simplify both equations first,
\n" ); document.write( " $\"3x%2B9y=33\"$
\n" ); document.write( "1. $\"x%2B3y=11\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"-10x-6y=-14\"$
\n" ); document.write( "2. $\"-5x-3y=7\"$
\n" ); document.write( "Add them together to eliminate y.
\n" ); document.write( " $\"x%2B3y-5x-3y=11%2B7\"$
\n" ); document.write( " $\"-4x=18\"$
\n" ); document.write( " $\"highlight%28+x=-9%2F2+%29+\"$
\n" ); document.write( "Then use either equation to solve for y.
\n" ); document.write( " $\"x%2B3y=11\"$
\n" ); document.write( " $\"-9%2F2%2B3y=11\"$
\n" ); document.write( " $\"3y=22%2F2%2B9%2F2\"$
\n" ); document.write( " $\"3y=31%2F2\"$
\n" ); document.write( " $\"highlight%28y=31%2F6%29+\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
