Chapter 1 LINEAR EQUATIONS 1.1 Introduction to linear equations A linear equation in n unknowns x1, x2,···, xn is an equation of the form a1x1 +a2x2 +···+anxn = b, where a1, a2,...,an, b are given real numbers. For example, with x and y instead of x1 and x2, the linear equation 2x+3y = 6 describes the line passing through the points (3, 0) and (0, 2).
