Explanation:

(2.1, -1.3)

Step-by-step explanation:

Each line represents the set of points that satisfy the equation.

That means there's only one point that satisfies both equations (and thus, is the solution) - the point where they cross.

We can see it's a bit to the right of x=2 and a bit lower then y=-1, so the (2.1, -1.3) point looks like the most plausible estimate.
