z = –42

B.
z = –34

C.
z = –30

D.

Answer 3

We want to isolate Z right? So start by subratcing the 2 from both sides

Answer 4

0 and 10?

Answer 5

yes so the 2 cancels out now we want to multiply by the reciprocal what is 10 x 3 = ?

Answer 6

30

Answer 7

sorry we skiped a step when we flip it would turn to -x therefore what is -3 x 10= ?

Answer 8

-30

Answer 9

Right so you get z=-30 :)
