1. $\"4x-2y=2+\"$
\n" ); document.write( "2. $\"y=-4x-7\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"4x-2%28-4x-7%29=2\"$
\n" ); document.write( " $\"4x%2B8x%2B14=2\"$
\n" ); document.write( " $\"12x=-12\"$
\n" ); document.write( " $\"highlight%28x=-1%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"y=-4%28-1%29-7\"$
\n" ); document.write( " $\"y=4-7\"$
\n" ); document.write( " $\"highlight%28y=-3%29\"$ \n" ); document.write( "

\n" );
