y=-2x-12
\n" ); document.write( "y=x-3
\n" ); document.write( "-2x-12=x-3
\n" ); document.write( "-2x-x=-3+12
\n" ); document.write( "-3x=9
\n" ); document.write( "x=9/-3
\n" ); document.write( "x=-3 ans.
\n" ); document.write( "y=-3-3
\n" ); document.write( "y=-6 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "-6=-2*-3-12
\n" ); document.write( "-6=6-12
\n" ); document.write( "-6=-6 \n" ); document.write( "
