Use slack variables to convert the constraints into linear equations.Maximizez = x1 + 2x2 + 3x3subject to:x1 + 4x2 + 3x3 ? 40 9x1 + x2 + 9x3 ? 50with:x1 ? 0, x2 ? 0, x3 ? 0
A. x1 + 4x2 + 3x3 + s1 = 40 9x1 + x2 + 9x3 + s2 = 50 B. x1 + 4x2 + 3x3 = s1 + 40 9x1 + x2 +9x3 = s2 + 50 C. x1 + 4x2 + 3x3 + s1 = 40 9x1 + x2 + 9x3 + s1 = 50 D. x1 + 4x2 + 3x3 = s1 - 40 9x1 + x2 +9x3 = s2 - 50
