Step-by-step explanation:
x-y=5-------(1)
xy=336------(2)
X= 5+y -----(3)
substitute 3 in 2
(5+y )y =336
y square +5y -336 = 0
y square + 21y -16 y - 366 =0
y ( y + 21) - 16 ( y + 21) =0
(y-16) ( y+21) = 0
therefore y = 16 and y= -21
since y cannot be negative
XY = 336
X= 336/ 16
x= 21
therefore X+Y = 37 ....
