Is there any method/way to determine the impact on demand/supply function QD = a - bP/ QS = a + - Economics - Market Equilibrium

Question

Is there any method/way to determine the impact on demand/supply

QD = a - bP/ QS = a + bP
due to change in factors like Price,Tax,Subsidy,Future Prices,price
of complementary and substitute goods etc

Dear student,

The standard demand and supply equations are based on the
relationship of quantity demanded and quantity supplied
respectively with the price of the commodity only while assuming
that other things remain the same
The impact of factors other than price is not depicted by the
demand equation and supply equation

Is there any method/way to determine the impact on demand/supply function QD = a - bP/ QS = a + bP due to change in factors like Price,Tax,Subsidy,Future Prices,price of complementary and substitute goods etc
