Pranav Delacruz · Answer 2

Answer: y=-9

Step-by-step explanation:

If a variable is by itself then the coefficient is always 1. Think of is as an imaginary 1. In this case since there is a negative in front of the variable it is - 1. Then, you divide each side by - 1. A positive divided by a negative equals a negative. y=-9

Example: - y=10

-y/-1 = y

10/-1 = - 10

Therefore, y=-10
