Send everything in demand and supply in English not French

Okay, here's a summary of demand and supply in English:

Demand refers to the quantity of a good or service that consumers are willing and able to purchase at various price levels, over a given period. The law of demand states that, all else being equal, the quantity demanded of a good decreases as its price increases, and vice versa.

Supply refers to the quantity of a good or service that producers are willing and able to sell at various price levels, over a given period. The law of supply states that, all else being equal, the quantity supplied of a good increases as its price increases, and vice versa.

The interaction of demand and supply in a market determines the equilibrium price and equilibrium quantity. The equilibrium price is the price at which the quantity demanded equals the quantity supplied. The equilibrium quantity is the amount of the good or service exchanged at that price.
