Whole numbers are numbers that are not fractions and do not include negative numbers an example is 0,1,2,3,4,5,....
so let's see if any numbers make the statements fale y is z less than x y=-z+x does this equal y+x=z? y=-z+x add z y+z=x subtract y z=-y+x not equal to z=y+x so first is not the answer
y is z more than x y=z+x subtract x y-x=z not equal to z=y+x so secod is not answer either
x is y less than z x=-y+z add y x+y=z this is equal to x+y=z to this is correct
xis y more than z x=y+z subtract y x-y=z this is not equal to x+y=z
Notice that since x and y are whole numbers, we can deduce that z is greater than either x or y. X or y cannot be negative.
Think of each option as an equation.
A. y = x - z B. y = x + z C. x = z - y D. x = z + y
We can discard the first option because if we subtract z, which is larger than both numbers, from x, we will get a negative number. Y is a whole number.
We can discard the second option because if we add x and z, we will get a quantity larger than y.
The third option is true.
x = z - y
Add y to both sides. x + y = z
Exactly the same as the original equation. If you tried to solve for z in the other equations, you would find that you can't obtain the original equation.
