Answer:
Z = -11
Step-by-step explanation:
When dealing with variables, you want to get it alone so it instantly equals the number.
Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.
Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!
-5Z = 55
/-5 /-5
Z = -11
Just in case, we'll plug in -11 for Z and see if it works.
-5(-11) = 55
Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!
Hope this helped :)
