partial equilibrium

Problem 2. There are two goods: 2' = 1, 2. The markets for both goods are competitive. Suppose these two goods are perfect complements for each consumer, i.e. every consumer j's utility function is uj : min{a:1j, xgj}. Question 1. All else equal, if p; increases, how would pi change? Elaborate your answer with rigorous analysis. Now suppose that, instead of being perfect complements, the two goods are perfect substitutes for each other, i.e. every consumer j's utility function is Uj = 5613' + $2j. Question 2. All else equal, if 193 increases, how would pi change? Elaborate your answer with rigorous analysis
