1.\"7x%2B3y=12\"
\n" ); document.write( "2.\"3x%2B7y=6\"
\n" ); document.write( "From eq. 1,
\n" ); document.write( "\"3y=-7x%2B12\"
\n" ); document.write( "\"y=-%287%2F3%29x%2B4\"
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( "\"3x%2B7%28-%287%2F3%29x%2B4%29=6\"
\n" ); document.write( "\"3x-%2849%2F3%29x%2B28=6\"
\n" ); document.write( "\"9x-49x%2B84=18\"
\n" ); document.write( "\"-40x=-66\"
\n" ); document.write( "\"highlight%28x=33%2F20%29\"
\n" ); document.write( "Then using eq.1,
\n" ); document.write( "\"231%2F20%2B3y=240%2F20\"
\n" ); document.write( "\"3y=9%2F20\"
\n" ); document.write( "\"highlight%28y=3%2F20%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
