From eq. 1,
\n" ); document.write( " $\"x=-3y%2B18\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"8%28-3y%2B18%29%2B4y=24\"$
\n" ); document.write( " $\"-24y%2B144%2B4y=24\"$
\n" ); document.write( " $\"-20y=-120\"$
\n" ); document.write( " $\"y=6\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"x=-3%286%29%2B18\"$
\n" ); document.write( " $\"x=-18%2B18\"$
\n" ); document.write( " $\"x=0\"$ \n" ); document.write( "

\n" );
