Simple linear equations resources

In this unit we give examples of simple linear equations and show you how these can be solved. In any equation there is an unknown quantity, x say, that we are trying to find. In a linear equation this unknown quantity will appear only as a multiple of x, and not as a function of x such as x², x³, sin x and so on. Linear equations occur so frequently in the solution of other problems that a thorough understanding of them is essential.
