1. $\"y-2x=1\"$
\n" ); document.write( "2. $\"2y%2B3x=16\"$
\n" ); document.write( "Multiply eq. 1 by (-2),
\n" ); document.write( "1. $\"-2%28y-2x%29=%28-2%291\"$
\n" ); document.write( "1. $\"-2y%2B4x=-2\"$
\n" ); document.write( "Now add it to eq. 2 to get rid of y,
\n" ); document.write( " $\"-2y%2B4x%2B2y%2B3x=-2%2B16\"$
\n" ); document.write( " $\"7x=14\"$
\n" ); document.write( " $\"highlight%28x=2%29\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( "1. $\"y-2x=1\"$
\n" ); document.write( " $\"y-2%282%29=1\"$
\n" ); document.write( " $\"y-4=1\"$
