Question: Consider the following problem. MaxZ = - 2 x 1 + x 2 - 4 x 3 + 3 x 4 subject to x 1

Consider the following problem.
MaxZ=-2x1+x2-4x3+3x4
subject to
x1+x2+3x3-x44
x1-x3+x4-1
2x1+x22
x1+2x2+x3+2x4=4
No nonnegativity constraint for x1,x20,x30,x40
Jsing the Big M method, work through the simplex method step by step to solve the problem.
Consider the following problem. MaxZ=-2x1+x2-4x3+3x4 subject to x1+x2+3x3-x44 x1-x3+x4-1 2x1+x22 x1+2x2+x3+2x4=4
