1. $\"x+%2B+y=-1\"$
\n" ); document.write( "2. $\"4x-3y=24\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Multiply eq. 1 by 3 and add to eq. 2 to eliminate $\"x\"$ ,
\n" ); document.write( " $\"3x%2B3y%2B4x-3y=-3%2B24\"$
\n" ); document.write( " $\"7x=21\"$
\n" ); document.write( " $\"highlight%28x=3%29\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$ .
\n" ); document.write( " $\"3%2By=-1\"$
\n" ); document.write( " $\"highlight%28y=-4%29\"$ \n" ); document.write( "

\n" );
