Substitute the second eq. into the first equation.
\n" ); document.write( "\"x-2%28-4x%2B24%29=-3\"
\n" ); document.write( "\"x%2B8x-48=-3\"
\n" ); document.write( "\"9x=45\"
\n" ); document.write( "\"highlight%28x=5%29\"
\n" ); document.write( "Then from the second equation,
\n" ); document.write( "\"y=-4%285%29%2B24\"
\n" ); document.write( "\"y=-20%2B24\"
\n" ); document.write( "\"highlight%28y=4%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
