Mathematics

6 0

Answer:

z = -1

Step-by-step explanation:

You must first start out by adding 19 to both sides to isolate the variable z, which results in:

2z = -2

Now, you can just divide by two on both sides to get z completely on its own, which gives you:

z = -1

Hope this helped somewhat! :D
