Use slack variables to convert the constraints into linear equations.Maximizez = 3x1 + 5x2subject to:5x1 + 4x2 ? 30 x1 + 2x2 ? 40with:x1 ? 0, x2 ? 0
A. 5x1 + 4x2 = s1 + 30
x1 + 2x2 = s2 + 40
B. 5x1 + 4x2 + s1 = 30
x1 + 2x2 + s2 = 40
C. 5x1 + 4x2 + s1 ? 30
x1 + 2x2 + s2 ? 40
D. 5x1 + 4x2 + s1 = 30
x1 + 2x2 + s1 = 40
