Answer:
Step-by-step explanation:
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
