You can put this solution on YOUR website!
The solution to the two equations that you chose are not -4 and 8 but X = -4/13, Y = 32/13
\n" ); document.write( "why do you think that -4 and 8 would be the solutions?
\n" ); document.write( " 5X-Y=-4
\n" ); document.write( "5*4-8=a
\n" ); document.write( "-20-8=-28
\n" ); document.write( " 5X-Y=-28 \r
\n" ); document.write( "\n" ); document.write( "6X+4Y=8
\n" ); document.write( "and 6(-4)+4*8=b.
\n" ); document.write( " -24+32=8
\n" ); document.write( "6X+4Y=8
\n" ); document.write( "which is the original equation you had
\n" ); document.write( "6X+4Y=8,
\n" ); document.write( "5X-Y=-28
\n" ); document.write( "now the solution is x=-4 and y=8
\n" ); document.write( "(-4, 8)\r
\n" ); document.write( "\n" ); document.write( "
