Suppose products A and B have demand and supply equations that are related to each other. If QA
and QB are the quantities produced and sold of A and B, respectively, and PA and B are their
respective prices, the table below shows the demand equations and the supply equations. Eliminate
QA and qB to get the equilibrium prices.
demand equations
9A =7-PA +1
+ PB
9B = 26+ PA - PB
supply equations
- 5+ 6PA - 3PB
9A
= -
==
QB-7-3pд+6PB
The prices are PA = $|
and
PB
= $
