QUESTION

Consider the following LP problem:
Maximize earnings = $0.80X1 + $0.40X2 + $1.20X3 - $0.10X4
subject to
X1 + 2X2 + X3 + 5X4 ≤ 150
X2 - 4X3 + 8X4 = 70
6X1 + 7X2 + 2X3 - X4 ≥ 120
X1, X2, X3, X4 ≥ 0
Q: The constraint X2 - 4X3 + 8X4 = 70, when converted to an = constraint for use in the simplex algorithm, will be
