Convert the constraints into linear equations by using slack variables.Maximize z = 4x1 + 12x2 + 7x3Subject to: 5x1 + 2x2 + x3 ? 12 x1 + 6x2 + x3 ? 24 x1 ? 0, x2 ? 0, x3 ? 0
A. 5x1 + 2x2 + x3 + s1 = 12 x1 + 6x2 + x3 + s2 = 24 B. 5x1 + 2x2 + x3 = s1 + 12 x1 + 6x2 + x3 = s2 + 24 C. 5x1 + 2x2 + x3 + s1 = 12 x1 + 6x2 + x3 + s1 = 24
