Question

If xand y are two integer such that x is the prodecessor of y ,then find the value of (x-y) and (x+y)​

Answer 1

Answer:

Step-by-step explanation:

According to question x is predecessor of y.

So,

   y=x+1

   x=y-1

So,

    x-y

  =y-1-y                                      [As x=y-1]

  =-1

So,

    x+y

  =y-1+y                                    [As x=y-1]

  =2y-1                                    

Please pardon me if i made a mistake.
