Solve the following system of inequalities graphically:
3x + 4y ≤ 60, x + 3y ≤ 30, x ≥ 0, y ≥ 0
3x + 4y ≤ 60,
Putting value of x = 0 and y = 0 in equation one by one, we get value of
y = 15 and x = 20
The required points are (0, 15) and (20, 0)
Checking if the origin lies in the required solution area (0,0)
0 ≤ 60, this is true.
Hence the origin would lie in the solution area of the line`s graph.
The required solution area would be on the left of the line`s graph.
x +3y ≤ 30,
Putting value of x = 0 and y = 0 in equation one by one, we get value of
y = 10 and x = 30
The required points are (0, 10) and (30, 0)
Checking for the origin (0, 0)
0 ≤ 30, this is true.
Hence the origin lies in the solution area which is given by the left side of the line`s graph.
x ≥ 0,
y ≥ 0,
The given inequalities imply the solution lies in the first quadrant only.
Hence the solution of the inequalities is given by the shaded region in the graph.
