Rewrite the system of inequalities, adding slack variables or subtracting surplus variables as needed.x1 + x2 + x3 ? 44x1 + x2 + x3 ? 21x1 + x2 ? 14
A. x1 + x2 + x3 - s1 = 44 x1 + x2 + x3 + s2 = 21 B. x1 + x2 + x3 - s1 = 44 x1 + x2 + x3 + s2 = 21 x1 + x2 + s3 = 14 C. x1 + x2 + x3 + s1 = 44 x1 + x2 + x3 - s2 = 21 x1 + x2 - s3 = 14 D. x1 + x2 + x3 + s1 = 21 x1 + x2 + x3 - s2 = 44
