6x+4y=-12 multiply by 8.
\n" ); document.write( " 8x-14y=-16 multiply by -6 & add.
\n" ); document.write( "48x+32y=-96
\n" ); document.write( "-48x+84y=96
\n" ); document.write( "-----------------
\n" ); document.write( "116y=0
\n" ); document.write( "y=0 ans.
\n" ); document.write( "6x+4*0=-12
\n" ); document.write( "6x=-12
\n" ); document.write( "x=-12/6
\n" ); document.write( "x=-2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "8*-2-14*0=-16
\n" ); document.write( "-16=-16 \n" ); document.write( "
