Linear relationships

In many business applications, two quantities are related linearly. This means a graph of their relationship forms a straight line. This leaflet discusses one form of the mathematical equation which describes linear relationships.

Simple linear equations

This leaflet shows how simple linear equations can be solved by
performing the same operations on both sides of the equation.

Solving linear equations

Equations always involve one or more unknown quantities which we try to find when we solve the equation. The simplest equations to deal with are linear equations. On this leaflet we describe how these are solved.
