$\"x+-+2y+=+-4\"$
\n" ); document.write( " $\"2x+-+y+=+1\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"x=2y-4\"$
\n" ); document.write( "Substitute into eq. 2,
\n" ); document.write( " $\"2%282y-4%29-y=1\"$
\n" ); document.write( " $\"4y-8-y=1\"$
\n" ); document.write( " $\"3y=9\"$
\n" ); document.write( " $\"y=3\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"x=2%283%29-4\"$
\n" ); document.write( " $\"x=6-4\"$
\n" ); document.write( " $\"x=2\"$
\n" ); document.write( " \n" ); document.write( "
