Question

The equation x + y = z relates the whole numbers x, y, and z. How does z compare to x? Y is z less than x. Y is z more than x. X is y less than z. X is y more than z.

Answer 1

x is y less than z

Explanation:

The given equation is x + y = z

This equation relates the whole numbers x, y, and z.

This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.

Making y the subject of the formula, it becomes

y = z-x (this shows that z is greater than y by x)

Making x the subject of the formula, it becomes

x = z-y (this shows that z is greater than x by y)

Looking at the options given, the correct comparisons between z and x is

x is y less than z
