1. $\"4x-3y=28\"$
\n" ); document.write( "2. $\"9x-y=-6\"$
\n" ); document.write( "Multiply eq. 2 by $\"-3\"$ and add to eq. 1,
\n" ); document.write( " $\"4x-3y%2B%28-27x%2B3y%29=28%2B18\"$
\n" ); document.write( " $\"-23x=46\"$
\n" ); document.write( " $\"x=-2\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$
\n" ); document.write( " $\"9%28-2%29-y=-6\"$
\n" ); document.write( " $\"-18-y=-6\"$
\n" ); document.write( " $\"-y=12\"$
\n" ); document.write( " $\"y=-12\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
