#### Answer:

Solve for x in one equation in order to substitute it into the other equation and you'll work through to get (-2,-6)

#### Explanation:

Let's start with the original equations:

We can solve the 2nd equation for x, then substitute that into the first equation. So let's first take the 2nd equation:

and add 28 to both sides to get:

We can now substitute that into the first equation:

now let's solve for y:

We can now substitute in the y value into one of our equations to find the x value. I'm going to use

Now let's check the answer:

So the final answer is (-2,-6)
