Add the equations together,
\n" ); document.write( "\"4x-y-4x-4y=-33%2B68\"
\n" ); document.write( "\"-5y=35\"
\n" ); document.write( "\"highlight%28y=-7%29\"
\n" ); document.write( "Now use either equation to solve for \"x\".
\n" ); document.write( "\"4x-y=-33\"
\n" ); document.write( "\"4x%2B7=-33\"
\n" ); document.write( "\"4x=-40\"
\n" ); document.write( "\"highlight%28x=-10%29\"
\n" ); document.write( "
\n" );
