Linear Programming QuestionSolutionR2 R22 x1 2 x3 x42 52 R

Linear Programming Question:

R2-> R2/2

x1 /2 + x3 -x4/2 = 5/2

R3->R3+6R2

3x1 +x2-x4 = -9

a) This problem is a minimisation problem whereas the constraints are less than equal to type

b) obj fn = 4x3-6x4

there is no limit to x4 therefore the equation can assume any value
