x=6.2
Answer:
Step-by-step explanation:
Given that the equation x + y = z relates the whole numbers x, y, and z.
This implies x,y,z all three are whole numbers
Hence we get x+y =z
x = z-y
where y is a whole number
So y can be 0,1,2.....
From this we can say x can take at most the value z in case y =0 other wise x has to be less than z
So comparison of x,y,z would give

( the equality applying only when y =0)
