Answer: y = -2 | is your answer
Step-by-step explanation: If you know what the value of x is then this problem is very easy. x= -3 so we just have to substitute it back into the original problem. When we do this we get y= -2. also in the future you can do the same thing if you are given y and asked to find x. Just plug in what you know and solve.
Hope this helps you, have a great day.
