From the first equation,
and substituting into the second gives
Answer:
Consider the system of equations,
and
As we know that,
'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.
So, after plotting the given graphs, we see that,
The only intersection point is (0.714,-2.857).
Thus, the solution of the system is x= 0.714 and y= -2.857.
