6x+3y=-12
\n" ); document.write( "-(6x+2y= -4) subtract.
\n" ); document.write( "-----------------
\n" ); document.write( "y=-8 ans.
\n" ); document.write( "6x+3*-8=-12
\n" ); document.write( "6x-24=-12
\n" ); document.write( "6x=-12+24
\n" ); document.write( "6x=12
\n" ); document.write( "x=12/6
\n" ); document.write( "x=2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "6*2+2*-8=-4
\n" ); document.write( "12-16=-4
\n" ); document.write( "-4=-4
\n" ); document.write( " \n" ); document.write( "
