In this topic, you learn combining like terms, which is a process that can and will be used in the broader topic of simplifying expressions.
In this topic, you further go in depth about the distributive property, such as learning about distributing terms with variables and distributing them to other terms with the same/different variables.
In this topic, you will combine your knowledge of solving one and two-step equations along with combining like terms and the distributive property to solve multi-step equations.
In this equation, yet another layer of depth will be added to algebraic equations, with variables now being on both sides of the equation.
