Question

Given the demand nda supply functions for three inter-dependent commodities 

QD1 = 45-2P1 + 2P2 -2P3

QD2 = 16+2P1+P2+2P3

QD3 = 30- P1+2P2-P3 

and

QS1 = -5+2P1

QS2 = -4 + 2P2

QS3 = -5 + P3 respectively.

Find the equilibrium prices and quantities of this three - commodity market model.
