Question

What is the solution to the equation?

2 - z/3 = 12

A. z = –42

B. z = –34

C. z = –30

D. z = 42

Answer 1

start by subtract ing 2 from both sides

second step, multiply both sides by -3

Answer 2

I got -36

Answer 3

Is the answer B?

Answer 4

\[2-\frac{z}{3}=12\]
Subtract 2 from both sides\[2-\frac{z}{3}-2=12-2\]
The twos cancel on the left\[-\frac{z}{3}=12-2\]
Multiply both sides by -3\[-3\left( -\frac{z}{3} \right)=-3(12-2)\]
The negative threes cancel on the left
\[z=-3(12-2)\]
subtract 2 from 12, then multiply by -3

Answer 5

So the answer is C.

Answer 6

Yep.
