1. $\"9x-6y=-12\"$
\n" ); document.write( "2. $\"x%2B2y=0\"$
\n" ); document.write( "From eq. 2,
\n" ); document.write( " $\"x=-2y\"$
\n" ); document.write( "Substitute into eq. 1,
\n" ); document.write( " $\"9%28-2y%29-6y=-12\"$
\n" ); document.write( " $\"-18y-6y=-12\"$
\n" ); document.write( " $\"-24y=-12\"$
\n" ); document.write( " $\"highlight%28y=1%2F2%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"x=-2%281%2F2%29\"$
\n" ); document.write( " $\"highlight%28x=-1%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
