X is greater than or = 0
X+Y is less than or equal to 4
2x+y is less than or equal to 5
For the inequalities we make auxiliary equations.
x=0 ,x+y=4, 2x+y=5
Then we make table for the equations and graph:
Then shade the regions according to the inequalities.
So the common region is the shaded region in black.
Solve the system of equations, please:
