: x + 2Y less than or equal to 3, x greater than or equal to 0, y greater than or equal to 0, find the maximum value of 2x + y

: x + 2Y less than or equal to 3, x greater than or equal to 0, y greater than or equal to 0, find the maximum value of 2x + y

x+2y=0,y>=0
If 2x + y is to be the maximum, X is to be the maximum, which is 3
So the maximum value of 2x + y is 6
