Find the minimum and maximum values of the objective function, and the points at which these values occur subject to the given constraints. Objective Function Constraints
f(x, y) = 7x + 6y
x=0
y=0
x+y = 3

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

whatvare the choices

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
