Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)
Now let's add this new equation and our second equation.
We found x=-3
Now let's plug x's value in one of the equations to find y's value.
So we found y=5
Solution ;
(-3, 5)

Answer:
Rise over run
Step-by-step explanation:
Take two points where you know for sure the coordinates (in this problem, you can use (2, 1.5) and the origin). Find the difference between the two y's for your run, and between your two x's for your rise. Then, put it in a fraction (it needs to be a fraction, thus the name rise over run.)
The equation of a circle always follows this:
(x - x1) + (y - y1) = r^2
x1 and y1 represent the coordinates as POSITIVE numbers and the r represent the radius
Your answer is (x + 1) + (y - 4) = 3
