\n" ); document.write( " $\"y+=+2x+-+1\"$ ....eq.1
\n" ); document.write( " $\"y+=+x+%2B+1\"$ ....eq.2
\n" ); document.write( "________________________\r
\n" ); document.write( "\n" ); document.write( "since left sides both equal, then right sides must be equal too\r
\n" ); document.write( "\n" ); document.write( " $\"+2x+-1=x+%2B+1\"$ ..........solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+2x+-x=1+%2B+1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+highlight%28x=2%29\"$ \r
\n" ); document.write( "\n" ); document.write( "go to\r
\n" ); document.write( "\n" ); document.write( " $\"y+=+x+%2B+1\"$ ....eq.2 plug in $\"2\"$ for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y+=+2+%2B+1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28y+=+3%29\"$ \r
\n" ); document.write( "\n" ); document.write( "so, lines intersect at point ( $\"2\"$ , $\"3\"$ )\r
