x+xy=8 xy=-x+8 y=-1+8/x
That is irrelevant, there is not possible way y=xy, and there is no possible way xy=x.
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
It is then x/y when simplified
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
It is XY^2 or X*Y*Y
The GCF is xy
Xy/y = x

Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
(x-y) + (xy - 1) = (x - 1)(y + 1)
*Hint*=xy=x mutiplied by y.
x+xy=8 xy=-x+8 y=-1+8/x
xy = x ÷x y = 1
If you mean: xy2/xy then it can be simplified to y
