2x+2y=56
\n" ); document.write( "xy=192
\n" ); document.write( "x=192/y
\n" ); document.write( "2(192/y)+2y=56
\n" ); document.write( "384/y+2y=56
\n" ); document.write( "(384+2y^2)/y=56
\n" ); document.write( "2y^2+384=56y
\n" ); document.write( "2y^2-56y+384=0
\n" ); document.write( "2(y^2-28y+192)=0
\n" ); document.write( "2(y-16)(y-12)=0
\n" ); document.write( "y-16=0
\n" ); document.write( "y=16 answer.
\n" ); document.write( "2x+2*16=56
