Answer:
The solution of the equation graphically are (-3,0) and (4,-7).
Step-by-step explanation:
Given : Equation 
To find : Solve the equation using graph?
Solution :
Let
be the equation (1)
be the equation (2)
If we plot the equation (1) and (2) in the graph then the intersection point gives you the solution of the equation.
Equation (1)
is shown in blue line.
Equation (2)
is shown in red line.
The intersection points of both the equation are (-3,0) and (4,-7).
Therefore, The solution of the equation graphically are (-3,0) and (4,-7).
Refer the attached figure below.
