Answer:
The solution of the system is at point (1,6) and (7,0).
Step-by-step explanation:
Given : System of equation
and 
To find : Solve the system of equation?
Solution :
We solve the equation graphically as the intersection points give you the solution of the system.
The equation given is one linear and one parabolic.
(1)
is a linear equation in red line passes through (0,7) and (7,0).
(2)
is a parabolic equation in blue line passes through (-1,0) and (7,0)
The intersection point of the equations are (1,6) and (7,0).
<u>Refer the attached figure below.</u>
Therefore, The solution of the system is at point (1,6) and (7,0).
