1. $\"5x%2B2y=-4\"$
\n" ); document.write( "2. $\"x-3y=5\"$
\n" ); document.write( "From eq. 2,
\n" ); document.write( " $\"x-3y=5\"$
\n" ); document.write( " $\"x=5%2B3y\"$
\n" ); document.write( " $\"5%285%2B3y%29%2B2y=-4\"$
\n" ); document.write( " $\"25%2B15y%2B2y=-4\"$
\n" ); document.write( " $\"17y=-29\"$
\n" ); document.write( " $\"y=-29%2F17\"$
\n" ); document.write( "From eq. 2 above,
\n" ); document.write( " $\"x=5%2B3y\"$
\n" ); document.write( " $\"x-y=5%2B3y-y=5%2B2y\"$
\n" ); document.write( " $\"x-y=5%2B2%28-29%2F17%29\"$
