An increase in demand can be expected to ["increase", "decrease"] equilibrium price and ["decrease", "increase"] equilibrium quantity.
An increase in supply can be expected to ["decrease", "increase"] equilibrium price and ["decrease", "increase"] equilibrium quantity.
If there is an increase in demand and an increase in supply then we can expect equilibrium price to ["increase", "stay the same", "it is not possible to say", "decrease"] and equilibrium quantity to ["decrease", "stay the same", "increase", "it is not possible to say"]
