this is the problem "A corporation wants to lease a fleet of 12 airplanes with a combined carrying capacity of 220 passengers. the three available types of planes carry 10,15, and 20 passengers., respectively. they want to know how many of each type of plane should be leased. write a system of equations and solve it using matrices. with your solution determine the options available to the corporation. (Hint: use the fact that no variable can be negative or greater than the total number of planes leasedto zome up with the options. In other words, require 0 ≤ x ≤ 12, 0 ≤ y ≤ 12 and 0 ≤ z ≤ 12. Note that you will have 3 variables and 2 equations."
these are the equations that I got from it x+y+z=12 and 10x+15y+20z=220 but when i out that in my ti83 this is what i keep getting
{1 0 -1 -8}
{0 1 2 20}
is this the answer if not what am I doing wrong?
