Solving an equation with exponents doubts

25 Views Asked by At

I have a demand function x = p^(-ed) and a supply function y = p^(-es)

Obviously this is an economics question, but to give some idea - I need to equate demand and supply, and find the equilibrium price - which is p in the equations. (And just a note, ed and es refer to the elasticities of demand and supply)

I don't understand how to solve this?
