\n" ); document.write( " $\"2y=2x%2B6\"$ ....eq.1
\n" ); document.write( " $\"y=2x%2B4\"$ ....eq.2
\n" ); document.write( "-----------------------\r
\n" ); document.write( "\n" ); document.write( "since in eq.2 $\"y\"$ is expressed in terms of $\"x\"$ , substitute it in eq.1\r
\n" ); document.write( "\n" ); document.write( " $\"2%282x%2B4%29=2x%2B6\"$ ....eq.1, solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4x%2B8=2x%2B6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4x-2x=6-8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x=-2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=-1\"$ \r
