Answer:


Step-by-step explanation:
The question and the attached image are different. However, the attached image answers the question y = -4 correctly.
So, I will solve for: 
Given

Required
Possible values of x and y
Let x = 0:



So, we have:

Let y = 4

So, we have:

<em>So, all you need to do is: assume a value for either x or y, then solve for the other variable.</em>
x=-3 and y= 7 will be you answer beautiful
