Answer 1

Answer:

Given x + y ≤ 3 -2x + y ≤ 3 or, x + y = 3 ...(i) -2x + y = 3 ...(ii) from equation (i) and (ii), we get x + y = 3 x 2 -2x + y = 3 (2x + 2y = 6) - (-2x + y = 3) y = 3 Then value of x = 2x + 6 = 6 2x = 0 x = 0

Step-by-step explanation:

The other values of x and y can be determined by this way the value of x and y are (2,0),(0,3),(3,0) and (0,2) x,y : z = y - 2x (2,0) : 2 - 0 = 2 (3,0) : 3 - 0 = 3 (0,3) : 0 - 6 = -6 (0,2) : 0 - 4 = -4
