1. $\"7x+-+y=+-1\"$
\n" ); document.write( "2. $\"y=+14x%2B5\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"7x-%2814x%2B5%29=-1\"$
\n" ); document.write( " $\"7x-14x-5=-1\"$
\n" ); document.write( " $\"-7x=4\"$
\n" ); document.write( " $\"highlight%28x=-4%2F7%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"y=14%28-4%2F7%29%2B5\"$
\n" ); document.write( " $\"y=-8%2B5\"$
\n" ); document.write( " $\"highlight%28y=-3%29\"$ \n" ); document.write( "

\n" );
