1. $\"3x%2B2y=-1\"$
\n" ); document.write( "2. $\"x-4y=3\"$
\n" ); document.write( "Mutiply eq. 1 by 2 and add to eq. 2,
\n" ); document.write( " $\"6x%2B4y%2Bx-4y=-2%2B3\"$
\n" ); document.write( " $\"7x=1\"$
\n" ); document.write( " $\"highlight%28x=1%2F7%29\"$
\n" ); document.write( "Then use either equation to solve for $\"x\"$
\n" ); document.write( " $\"2y=-1-3x\"$
\n" ); document.write( " $\"2y=-1-3%281%2F7%29\"$
\n" ); document.write( " $\"2y=-7%2F7-3%2F7\"$
\n" ); document.write( " $\"2y=-10%2F7\"$
\n" ); document.write( " $\"highlight%28y=-5%2F7%29\"$ \n" ); document.write( "
