4. Solve the following LP graphically (next page for graph paper). Make sure to identify the two binding constraints (or equations) that determine the optimal point and use these equations to determine the optimal values of xland x2. [5 points] Max Z = 3 x1 + 8 X2 s.t. X1 + x2 $ 7 X1 - 3x2 $ 3 X2 - XI $ 3 X2 54 X1 , X2 2 0 (3, 0) = 3 (3) + 8(0) = 9 ( 6, 1 ) => 3 (6) + 8(1) = 26 (3, 4) => 3(3) + 8(4) = 41 ( 1, 4 ) => 3 (1) + 8 ( 4 ) -35 ( 0, 3) => 3(0) +8 (3) = 24
