So this question were asked to do this attraction and then also list any values for the variable X, which the fractions are not defined. So right off the bat, we can say that wife cannot be equal to zero, as that would make the denominator here equal to zero. And we can't have that. So to do the subtraction, we need Thio find a common denominator. So in this case, the common denominator would be too I So I would have to multiply five by two. I over to I, which gives me 10. Why? Over to y minus one of the two I. And so then this would combine into 10. Why minus one over to I, um c could, I guess, simplify this a little bit more after splitting the fraction. But that would just give you get you back to where we started. So we can just leave her answer like this. 10 Y minus one over to us.
