Max Z = X1 - X2 + 3X3

s.t. X1+X3 = 5

X1+X2 <= 20

X2+X3 >= 10

X1 , X2 , X3 >= 0

a) Put the problem into standard form, using slack, excess, and artificial variables.

b) Identify the initial BV and NBV along with their values.

c) Modify the objective function using an M, a large positive number.

d) Apply the Big M method to find the optimal solution
