उत्तर

To find graphical solution, construct the table as follows:

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

2(0) + 0 ≤ 2
∴ 0 ≤ 2

∴ origin side

x − y ≤ 1 x − y = 1 `x/1 + y/(-1)` = 1 A(1, 0)
C(0, −1)

0 - 0 ≤ 1
∴ 0 ≤ 1

∴ origin side

The shaded portion represents the graphical solution.
