1. $\"2x-6y=3\"$
\n" ); document.write( "2. $\"4x%2B9y=+-1\"$
\n" ); document.write( "Multiply eq. 1 by (-2) and add to eq. 2,
\n" ); document.write( " $\"-4x%2B12y%2B4x%2B9y=-6-1\"$
\n" ); document.write( " $\"21y=-7\"$
\n" ); document.write( " $\"highlight%28y=-1%2F3%29\"$
\n" ); document.write( "Then use either equation to solve for x.
\n" ); document.write( " $\"2x%2B2=3\"$
\n" ); document.write( " $\"2x=1\"$
\n" ); document.write( " $\"highlight%28x=1%2F2%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
