2x+2y=300 or 2x=300-2y or x=150-y
\n" ); document.write( "xy=5,000
\n" ); document.write( "(150-y)y=5,000
\n" ); document.write( "150y-y^2=5,000
\n" ); document.write( "y^2-150y+5,000=0
\n" ); document.write( "(y-100)(y-50)=0
\n" ); document.write( "y-100=0
\n" ); document.write( "y=100 & x=50 ans.
\n" ); document.write( "y-50=0
\n" ); document.write( "y=50 & x=100 ans.
