Convert the constraints into linear equations by using slack variables.Maximize z = 2x1 + 8x2Subject to: x1 + 6x2 ? 15 7x1 + 5x2 ? 25 x1 ? 0, x2 ? 0
A. x1 + 6x2 = s1 + 15
7x1 + 5x2 = s2 + 25
B. x1 + 6x2 + s1 ? 15
7x1 + 5x2 + s2 ? 25
C. x1 + 6x2 + s1 = 15
7x1 + 5x2 + s2 = 25
D. x1 + 6x2 + s1 ? 15
7x1 + 5x2 + s2 ? 25
