\n" ); document.write( "_________________________\r
\n" ); document.write( "\n" ); document.write( " $\"2y=-8x\"$ ..........eq.2...solve for $\"y\"$
\n" ); document.write( " $\"y=-4x\"$ ..........eq.2a\r
\n" ); document.write( "\n" ); document.write( "substitute in eq.1\r
\n" ); document.write( "\n" ); document.write( " $\"-14=3x-%28-4x%29\"$ .......eq.1\r

\n" ); document.write( "\n" ); document.write( " $\"x=-2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "go to eq.2a, substitute $\"+x\"$ \r
