x+2y=4
\n" ); document.write( "3x-2y=-12 now add
\n" ); document.write( "-----------------------
\n" ); document.write( "4x=-8
\n" ); document.write( "x=-8/2
\n" ); document.write( "x=-2 ans.
\n" ); document.write( "-2+2y=4
\n" ); document.write( "2y=4+2
\n" ); document.write( "2y=6
\n" ); document.write( "y=6/2
\n" ); document.write( "y=3 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "3*-2-2*3=-12
\n" ); document.write( "-6-6=-12
\n" ); document.write( "-12=-12 \n" ); document.write( "
