Chapter 3: Equation Systems
What you need to learn in this chapter
In this chapter, we will be learning about equation systems.
We will start by understanding systems of linear equations in three variables.
This means we will be dealing with equations that have three unknowns.
We will learn how to solve these systems of equations by using different methods such as substitution, elimination, and matrix methods.
Next, we will move on to simultaneous equations involving one linear equation and one non-linear equation.
We will learn how to solve these types of equations by substituting the value of one variable from one equation into the other equation.
This will help us find the values of the variables and solve the system of equations.
By the end of this chapter, we will be able to confidently solve equation systems with three variables and understand how to deal with simultaneous equations involving one linear and one non-linear equation.
