evaluate each expression if x = -19 , y = -15 and z = 16 . what is z-x-y ?

Answer:

z-x-y = (16-(-19)-(-15)) = (16+19+15) = 50

(Do not forget to change the sign inside the parentheses when you have a negative sign outside)

first, you would plug the answers into the appropriate spots in their equations:

z-x-y

(16)-(-19)-(-15)
(16)+(+19)+(+15)
16+19+15
35+15
50
