System of differential equations

System of differential equations are like a set of rules that help us figure out how different things are related to each other. It's like figuring out how a bunch of pieces of a big puzzle fit together. Differential equations make it easier to understand how small pieces of a puzzle change and how they fit together to make a bigger picture. For example, a differential equation might tell us how the pressure in a container of air will change over time if we change the temperature.
