Sections

What Are Simultaneous Equations?

Simultaneous equations involve solving multiple equations with shared variables, where the solution must satisfy all equations at once.

1 Section Overview

Start current section content and materials

Methods of Solving Simultaneous Equations

This section covers three methods for solving simultaneous equations: substitution, elimination, and graphical methods.

2 Section Overview

Start current section content and materials

2.1 Substitution Method

The substitution method is a technique for solving simultaneous equations by isolating one variable and substituting it into another equation.

2.2 Elimination Method

The elimination method is a technique used to solve simultaneous equations by eliminating one variable through addition or subtraction.

2.3 Graphical Method

The graphical method is a technique for solving simultaneous equations by plotting them on a coordinate plane and identifying their points of intersection.

Special Cases

This section covers the special cases of simultaneous equations including scenarios with no solutions and infinite solutions.

3 Section Overview
