Answer: All points in the shaded region after 2y<-12x+4 is the solution.
Step-by-step explanation:
Since we have given that
We need to find the point of solution to the system of inequalities:
Suppose
We first check the consistency of the system of equation:
So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.
Using zero test,
0<4 it is true so, shaded part is towards the center.
Similarly,
0<4 again it is true it would be shaded towards the center.
So, the common part will be after 2y<-12x+4 .
Hence, all the points in the shaded region is the solution.
