Chapter 13 builds on linear polynomials to study linear equations in two variables. Starting from a fruit-cart situation, it shows how such an equation describes a line and then explains how to solve a pair of linear equations.
Topics covered
- Linear equations in two variables
- Solutions of a linear equation as points on a line
- Solving a pair of linear equations
