From eq. 2,
\n" ); document.write( " $\"y=4x%2B11\"$
\n" ); document.write( "Substitute into eq. 1,
\n" ); document.write( " $\"2%284x%2B11%29%2B10x%2B18=4\"$
\n" ); document.write( " $\"8x%2B22%2B10x%2B18=4\"$
\n" ); document.write( " $\"18x=-36\"$
\n" ); document.write( " $\"x=-2\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"y=4%28-2%29%2B11\"$
\n" ); document.write( " $\"y=-8%2B11\"$
\n" ); document.write( " $\"highlight%28y=3%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
