1. $\"-8x+%2B+8y+=+-16\"$
\n" ); document.write( "2. $\"2x+%2B+6y+=+-28\"$
\n" ); document.write( "Multiply eq. 2 by 4 and add to eq. 1,
\n" ); document.write( " $\"-8x%2B8y%2B8x%2B24y=-16-112\"$
\n" ); document.write( " $\"32y=-128\"$
\n" ); document.write( " $\"highlight%28y=-4%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"2x-24=-28\"$
\n" ); document.write( " $\"highlight%28x=-2%29\"$ \n" ); document.write( "

\n" );
