Answer:

Explanation:
To work out the answer graphically, plot the graphs which i have attached in the screenshot below.
The red is the equation
and blue is the equation
.
When working out the values which satisfy the equations, we look at the point of intersection (the point where the two graphs meet). I labelled it in green giving our coordinates.
As you can see in the coordinates the x value is -2, but also the y value is also -2. This gives the answer
and
.
Hope this helps!!!
