What is linear congruence?
Definition. A linear congruence is a congruence relation of the form ax ? b (mod m) where a, b, m ? Z and m > 0. A solution is an integer x which makes the congruence relation true AND x is a least residue (mod m) (that is, 0 ? x ? m?1).What is linear congruence with example?
A congruence of the form ax?b(mod m) where x is an unknown integer is called a linear congruence in one variable. It is important to know that if x0 is a solution for a linear congruence, then all integers xi such that xi?x0(mod m) are solutions of the linear congruence.Different Methods to Solve Linear Congruences
