11) Use the echelon method to solve the system of three equations in three unknowns x - y + 4z = 19 2c + z = 4 x + 3y + z = -5

Echelon Method and maximization

11) Use the echelon method to solve the system of three equations in three unknowns

x - y + 4z = 19
2c + z = 4
x + 3y + z = -5

14) Find x1 is greater than or equal to 0 and x 2 is greater than or equal to 0 such that:

2x1 + 3x2 >/60
2x1 + 5x2

and z = 5x1 + 4x2 is maximized
