1. $\"3x-4y=6\"$
\n" ); document.write( "2. $\"-x%2By=-1\"$
\n" ); document.write( "Multiply eq.2 by 3 and add the equations,
\n" ); document.write( " $\"3x-4y-3x%2B3y=6-3\"$
\n" ); document.write( " $\"-y=3\"$
\n" ); document.write( " $\"highlight%28y=-3%29\"$
\n" ); document.write( "Then use either equaiton to solve for x.
\n" ); document.write( " $\"-x-3=-1\"$
\n" ); document.write( " $\"-x=2\"$
\n" ); document.write( " $\"highlight%28x=-2%29\"$
\n" ); document.write( " \n" ); document.write( "
