In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables. For example, is a system of three equations in the three variables x, y, z. A solution to a linear system is an assignment of numbers to the variables such that all the equations are ... A finite set of linear equations is called a system of linear equations or, more briefly, a linear system. The variables are called unknowns. For example, system (5) that follows has unknowns x and y, and system (6) has unknowns x 1, x 2, and x 3. 5x +y = 34x 1 −x 2 +3x 3 =−1 2x −y = 43x 1 +x 2 +9x 3 =−4 (5–6)We will see later in this chapter that when a system of linear equations is written using matrices, the basic unknown in the reformulated system is a column vector. A similar formulation will also be given in Chapter 7 for systems of differential equations. Example 2.1.5 The matrix a = ˘ 2 3 − 1 5 4 7 ˇ is a row 3-vector and b = 1 −1 3 4When solving a system of two equations of two unknowns, if you get an equation like 0 = 1, then there can be no solution. If, on the other hand, you get an equation like 0 = 0, then the system is (probably) dependent. Example 1: Consider the system 2x + y = 5 x – y = 1 . The solution is x = 2, y = 1. The lines intersect at the point (2,1).

4.3: Solving Systems by Elimination.
