Question

The equation x + y = z relates the whole numbers x, y, and z. How does z compare to x? If it helps, consider an example where you substitute 3 for x, 5 for y, and 8 for z.

Answer 1

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

$x\leq z$

( the equality applying only when y =0)
