\n" ); document.write( "2x-4y=6
\n" ); document.write( "-------------
\n" ); document.write( "7x=14
\n" ); document.write( "x=14/7
\n" ); document.write( "x=2 ans.
\n" ); document.write( "2-2y=3
\n" ); document.write( "-2y=3-2
\n" ); document.write( "-2y=1
\n" ); document.write( "y=1/-2
\n" ); document.write( "y=-1/2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "5*2+4*-1/2=8
