Which point is in the solution set of the given system of inequalities 3x+y> -3,x+2y< 4

Step 1. Solve both inequalities for :







Step 2. To check a point in the solution of the given system of inequalities, look for the intercepts of the lines  and :

(1)
(2)

Replace (1) in (2):

Solve for :

(3)

Replace (3) in (1):





We can conclude that the point (-2,3) is in the solution of the system if inequalities; also any point inside the dark shaded area of the graph of the system of inequalities is also a solution of the system.
