Answer:  z = -2

Step-by-step explanation:

The goal is to get the variable "z" alone, so we have to simplify it. You subtract 1 from each side, making the left side read "-3z" and the right simply have 6. You then have to get rid of the coefficient, which is the number that your variable (z) is being multiplied by. So you then divide each side by -3. You will be left with "z = -2" because 6 divided by -3 is equal to -2.
