Solve 3x-6y=12
\n" ); document.write( " 2x+6y=-12\r
\n" ); document.write( "\n" ); document.write( "By using elimination. Express your answer as an ordered pair.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3x-6y=12
\n" ); document.write( "+
\n" ); document.write( "2x+6y=-12
\n" ); document.write( "_________\r
\n" ); document.write( "\n" ); document.write( "5x=0
\n" ); document.write( "x=0\r
\n" ); document.write( "\n" ); document.write( "(Since the y's already canceled each other, I didn't have to multiply anything.)\r
\n" ); document.write( "\n" ); document.write( "Now plug the x-value in both equation and see if it works:\r
\n" ); document.write( "\n" ); document.write( "3(0)-6y=12
\n" ); document.write( "-6y=12
\n" ); document.write( "y=-2\r
\n" ); document.write( "\n" ); document.write( "2(0)+6y=-12
\n" ); document.write( "6y=-12
\n" ); document.write( "y=-2\r
\n" ); document.write( "\n" ); document.write( "So the answer is (0,-2)\r
