\n" ); document.write( " $\"y=x%2B6\"$ ......eq.1
\n" ); document.write( " $\"y=-2x\"$ ......eq.2
\n" ); document.write( "-------------------------\r
\n" ); document.write( "\n" ); document.write( "substitute $\"y\"$ from eq.2 in eq.1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"-2x=x%2B6\"$ ......eq.1, solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-2x%2B2x=x%2B2x%2B6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0=3x%2B6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0-6=3x%2B6-6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-6=3x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-6%2F3=x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=-2\"$ \r
\n" ); document.write( "\n" ); document.write( "go to eq.2\r
\n" ); document.write( "\n" ); document.write( " $\"y=-2x\"$ ......eq.2, substitute $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=-2%28-2%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=4\"$ \r
