You can put this solution on YOUR website!
Substitute -2x into the y in the second equation.
\n" ); document.write( "6x-2x=8
\n" ); document.write( "4x=8
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( "Now plug 2 into x in the first equation.
\n" ); document.write( "y=-2*2
\n" ); document.write( "y=-4\r
\n" ); document.write( "\n" ); document.write( "So there you have it: x = 2 and y = -4.
\n" ); document.write( "
\n" );
