Answer:
x is y less than z
Step-by-step 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
