Use the inverse matrix method to find the equilibrium prices and quantities where the supply and demand functions for each good are:

Qd1 = 50 – 2p1 + 5p2 - 3p3
Qd2= 22 + 7p1 – 2p2 + 5p3
Qd3= 17 + p1 + 5p2 – 3p3

Qs1 = 8p1 -5
Qs2 = 12p2 -5
Qs3 = 4p3 -1

Thanks, could you also let me know what you got for your inverse and cofactor matix.
