Solve the system of equations by graphing
The solution of the system of equations is the intersection point both graphs
The solutions are the points (1.545,-0.687) and (2.956,-22.835)
see the attached figure
The approximate solutions are
(1.5,-0.7) and (2.9,-22.8)
3 (3b+2)= -30
9b+ 6=-30
9b=-36
b=4
