Suppose y is a positive integer. if )=z will z be greater than x ?

Yes, z will be greater than x.

Step-by-step explanation:

Given expression is

now let y = 2 and x = 1

Then,

where i.e. 3 > 1

on simplifying the given  expression in terms of y

now suppose if x = 7 and z=3 then,

which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then  z will be greater than x.
