69) {x} = [A]->{C} . 69) is a very inefficient method of solving simultaneous equations, as operations on [A] have to take place both above and below the leading diagonal. There are a number of much more efficient methods of solving simultaneous equations, and some of these are described below. 1.

In most practical problems the condition that {x} is null is not of interest, hence the following should be satisfied. 91) is known as the characteristic equation.
