Use slack variables to convert the constraints into linear equations.Maximizez = 4x1 + 12x2 + 7x3subject to:6x1 + 2x2 + x3 ? 12 x1 + 9x2 + x3 ? 24with:x1 ? 0, x2 ? 0, x3 ? 0

A. 6x1 + 2x2 + x3 = s1 - 12
 x1 + 9x2 + x3 = s2 - 24
B. 6x1 + 2x2 + x3 = s1 + 12
 x1 + 9x2 + x3 = s2 + 24
C. 6x1 + 2x2 + x3 + s1 = 12
 x1 + 9x2 + x3 + s2 = 24
D. 6x1 + 2x2 + x3 + s1 = 12
 x1 + 9x2 + x3 + s1 = 24
