The non-permissible value(s) for x in the rational expression 10x / (2x - y) would be any value of x that makes the denominator equal to zero. In this case, we set the denominator (2x - y) equal to zero and solve for x:
2x - y = 0
2x = y
x = y/2
So, the non-permissible value for x is when x equals y/2.
Identify the non-permissible vaule(s) for x for each of following rational expression:
10x / 2x-y
