On a supply and demand graph you would see that the supply would meet the demand at the central point creating a secure system. However, this could change for the better or worse, compared to how "popular" the item is in the market.
In economics a Equilibrium state is a state where the economic forces such as the supply and demand are balanced and in the absence of external influences the values of economic variables will not change.
Hence market equilibrium is the actual price you see in the world is a balancing act between supply and demand.
Start by multiplying 1.2 and 7.5 which will give you 9.Then you have 9-8/4. so then you do 8 divided by 4 which is 2. so you have 9-2 and that equals 7.
