Abstract

A linear equation in n unknowns x1,…,xn is an equation of the form
$${a_1}{x_1} + {a_2}{x_2} + \ldots + {a_n}{x_n} = b,$$
where a1,a2,…,an,b are real or complex numbers, and are referred to as the coefficients of the equation. When n = 2 and a1, a2 are real, such an equation is the Cartesian equation of a straight line in ℝ2 (Fig. 3.1(a)); when n = 3 and a1 a2, a3 are real we have the Cartesian equation of a plane in ℝ3 (Fig. 3.1(b)); see section 1.5(f).
