1. $\"x%2F3%2B6y=4\"$
\n" ); document.write( "2. $\"y=-5-x\"$
\n" ); document.write( "Substitute eq. 2 directly into eq. 1,
\n" ); document.write( " $\"x%2F3%2B6%28-5-x%29=4\"$
\n" ); document.write( " $\"x%2F3-30-6x=4\"$
\n" ); document.write( "Multiply both sides by $\"3\"$ .
\n" ); document.write( " $\"x-90-18x=12\"$
\n" ); document.write( " $\"-17x=102\"$
\n" ); document.write( " $\"highlight%28x=-6%29\"$
\n" ); document.write( "Now use eq. 2,
\n" ); document.write( " $\"y=-5-%28-6%29%29\"$
\n" ); document.write( " $\"y=-5%2B6\"$
\n" ); document.write( " $\"highlight%28y=1%29\"$ \n" ); document.write( "

\n" );
