Write a matrix equation for the given systems of equations. Find the maximum and minimum values of the objective function f(x, y) and for what values of x and y they occur, subject to the given constraints. 2x - 6y - 2z = 1 3y - 2z = -5 2y+ 2z = -3 Ax, y) = 2x + 6y x20 2x + 7y = 70 O 2-6-2 X 8x + 4y = 136 3-2 -5 2+2 N max at (14, 6) = 64, min at (0, 0) = 0 2 -6 -2 X O 3 -2 y max at (15, 9) = 84, min at (0, 0) = 0 = -5 O 2 N max at (0, 10) = 60, min at (0, 0) = 0 N -6 -2 max at (17, 0) = 34, min at (0, 0) = 0 -2 0 -5 N O -3 N -6 -2 0 3 -2 -5 Y O 2
