# Question: For each of the following constraints of pure BIP problems

For each of the following constraints of pure BIP problems, use the constraint to fix as many variables as possible:

(a) 20x1 – 7x2 + 5x3 ≤ 10

(b) 10x1 – 7x2 + 5x3 ≥ 10

(c) 10x1 – 7x2 + 5x3 ≤ –1

(a) 20x1 – 7x2 + 5x3 ≤ 10

(b) 10x1 – 7x2 + 5x3 ≥ 10

(c) 10x1 – 7x2 + 5x3 ≤ –1
