\n" ); document.write( " $\"x-2y+=+-25\"$ .....eq.1
\n" ); document.write( " $\"3x+-y+=+0\"$ .....eq.2
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( " $\"x-2y+=+-25\"$ .....eq.1...solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=+2y+-25\"$ ...substitute in eq.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"3%282y+-25%29+-y+=+0\"$ .....eq.2..solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"6y+-75+-y+=+0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"5y=+75\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=+75%2F5\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=+15\"$ \r
\n" ); document.write( "\n" ); document.write( "now find $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=+2y+-25\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=+2%2A15+-25\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=30+-25\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=+5\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution is: \r
\n" ); document.write( "\n" ); document.write( " $\"x=+5\"$ and $\"y=+15\"$ \r
\n" ); document.write( "\n" ); document.write( "means, the intersection point of these two lines is at ( $\"5\"$ , $\"15\"$ )\r
