Solving linear
3.1
equations
Introduction
Many problems in engineering reduce to the solution of an equation or a set of equations. An
equation is a type of mathematical expression which contains one or more unknown quantities
which you will be required to find. In this Block we consider a particular type of equation
which contains a single unknown quantity, and is known as a linear equation. Later Blocks will
describe techniques for solving other types of equations.
