MATH 204 Summary Linear equation in the n variables x1, x2, … , xn to be on that can be expressed in the form: a1x1 a2x2 … anxn=b In special case where b = 0, it is called a homogeneous linear equation in the variables x1, x2, … , xn. A finite set of linear equations is called a system of linear equations or a linear system. The variables are called unknowns. A solution of a linear system in n unknowns can be written as (s1, s2, … , sn) which is called an ordered n-tuple. If n = 2,...
