I'm taking a special math class to in prove in a few areas before the real stuff begins. heres the 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.

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

therefor the answer is x is y less than z
