x+y=4
\n" ); document.write( "xy=-32
\n" ); document.write( "from the first equation x=4-y, plug that into second one
\n" ); document.write( " $\"%284-y%29y=-32\"$
\n" ); document.write( " $\"4y-y%5E2=-32\"$
\n" ); document.write( " $\"0=y%5E2-4y-32\"$ factor
\n" ); document.write( " $\"0=%28y-8%29%28y%2B4%29\"$
\n" ); document.write( "so y is 8 or y is -4, now you plug those into x=4-y and solve for x
\n" ); document.write( "x=4-8=-4 or x=4-(-4)=8
\n" ); document.write( "so looks lie the answer is (-4, 8) or (8, -4). Either way, the numbers are -4 and 8. \n" ); document.write( "
