Evaluate each of the following expressions if x=6, y=6, z=-3.
x+12=
x+3y+z=
(x-12)+3(y+z)=
100x+yz=

answer:

1.) 18   2.) 27   3.) 21   4.) 618

step-by-step explanation:

x=6 y=6 z=3

substitute the variables:

6+12=18

6+3*6+3 -> 6+18+3=27

(6-12)+3(6+3) -> -6+3*(6+3) -> -6+3*9 -> -6+27=21

100*6+6*3 -> 600+6*3 -> 600+18=618
