An integer is a whole number and the product of numbers means to multiply them. So so we know that: x * y = x - 50
So the product (x * y) is 50 less than one of the integers ( x - 50)
I can divide both sides by x: y = (x - 50) / x where x is not zero y = x/x - 50/x y = 1 - 50/ x
x can no longer be zero since you cannot divide by zero
the only way for y to be a whole number is if 50/x is a whole number. 50/x can onky be a whole number if x is a factor of 50. so take any factor of 50 and that will be possible answers. factors of 50: 1,2,5,10,25,50
these would be possible x values. To to find corresponding y values plug in x y = 1 - 50/1 y = 1 - 50 y = -49 So first pair is (1, -49) do the same for the rest and get (2, -24) (5, -9) (10, -4) (25, -1) (50, 0)
