3rd original equation

4. A manufacturer produces two items which are sold at prices of p_{1}
dollars and p_{2} dollars each. The supply and demand functions
in units for the items are as follows:

P(s_{1})
= the supply function for the first item.

P(d_{1})
= the demand function for the first item.

P(s_{2})
= the supply function for the second item.

P(d_{2})
= the demand function for the second item.

How should prices be set for each item to equate supply and demand? What are the equilibrium quantities for each item?
