The third equation is the correct one; it can be used to find the solution of this system of equations.

3

0 = ----- + x

x

... can be rewritten as

-3

----- = x

x

The yellow line has the equation y = x, and the curve has the equation

-3

----- = x

x

It can be seen directly from the graph that the solution is x = -3 and y = -3, or

(-3, -3)

x
