उत्तर

To find the feasible solution, construct the table as follows:

Inequation Equation Double
intercept form
Points
(x, y)
Region
2x + 3y ≤ 12 2x + 3y = 12 `x/6 + y/4` = 1 A(6, 0)
B(0, 4)

2(0) + 3(0) ≤ 12

∴ 0 ≤ 12

∴ origin side

2x + y ≤ 8 2x + y = 8 `x/4 + y/8` = 1 C(4, 0)
D(0, 8)

2(0) + 0 ≤ 8

∴ 0 ≤ 8

∴ origin side

x ≥ 0 x = 0 − − R.H.S. of Y-axis
y ≥ 0 y = 0 − − Above X-axis

The shaded portion represents the graphical solution.
