Question

Explain whether x-y>5 is a proposition or not?

Answer 1

A proposition has only two values:

x - y  >  5 

We need to substitute the values of x and y in the preposition.

If the value of arithmetic expression  (x - y) is  more than 5 then  the preposition is True.  

Otherwise, if the value of (x - y) is less than or equal to 5  then the preposition is false.

So, x - y  > 5  is a predicate or a preposition.
