Convert the constraints into linear equations by using slack variables.Maximize z = x1 + 2x2 + 3x3Subject to: x1 + 7x2 + 2x3 ? 40 5x1 + x2 + 4x3 ? 50 x1 ? 0, x2 ? 0, x3 ? 0
A. x1 + 7x2 + 2x3 + s1 = 40 5x1 + x2 + 4x3 + s1 = 50 B. x1 + 7x2 + 2x3 = s1 + 40 5x1 + x2 +4x3 = s2 + 50 C. x1 + 7x2 + 2x3 + s1 = 40 5x1 + x2 + 4x3 + s2 = 50
