\n" ); document.write( " $\"2y%2Bx=9\"$ ........eq.1\r
\n" ); document.write( "\n" ); document.write( " $\"x=3y-3\"$ .....eq.2
\n" ); document.write( "__________________________\r
\n" ); document.write( "\n" ); document.write( " $\"2y%2Bx=9\"$ ........eq.1......substitute $\"x\"$ from eq.2\r
\n" ); document.write( "\n" ); document.write( " $\"2y%2B3y-3=9\"$ .....solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"5y=9%2B3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"5y=12\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=12%2F5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28y=2.4%29\"$ \r
\n" ); document.write( "\n" ); document.write( "now, go back to $\"x=3y-3\"$ .....eq.2, substitute $\"2.4\"$ for $\"y\"$ and solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=3%2A2.4-3\"$ .....eq.2\r
\n" ); document.write( "\n" ); document.write( " $\"x=7.2-3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28x=4.2%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
