Question #218456

Solve the following Linear Programming (LP) problem:

Maximize Z = 3X1 + 2X2

Subject to: X1 + X2 ≤ 6

2X1 + X2 ≤ 8

-X1 + X2 ≤ 1

X2 ≤ 2

The function increases as x1x_1 and x2x_2 increase. The problem is considered in the following polygon:



We draw lines of the type z=3x1+2x2z=3x_1+2x_2, where we set z=c1,c2,...z=c_1,c_2,... with arbitrary cjc_j. We receive the picture:



It is clear that the maximum is achieved at the point C. It is situated at the intersection of lines x2=2x_2=2 and 2x1+x2=82x_1+x_2=8 . We get C=(3,2)C=(3,2). The maximum is: Z=13Z=13
