1. $\"5x=3y-4\"$
\n" ); document.write( "2. $\"5y=3x-4\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"x=%281%2F5%29%2A%283y-4%29\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( " $\"5y=%283%2F5%29%283y-4%29-4\"$
\n" ); document.write( " $\"25y=3%283y-4%29-20\"$
\n" ); document.write( " $\"25y=9y-12-20\"$
\n" ); document.write( " $\"16y=-32\"$
\n" ); document.write( " $\"highlight_green%28y=-2%29\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"5x=3%28-2%29-4\"$
\n" ); document.write( " $\"5x=-10\"$
\n" ); document.write( " $\"highlight%28x=-2%29\"$ \n" ); document.write( "

\n" );
