There are different systems of linear algebraic equations (SLAE). There are accurate and approximate methods. Iteration method is approximate one. It is very important because sometimes using approximate methods we can obtain results with grater accuracy than using accurate one. International method can be applied where accurate method cannot be used. Iteration method can be applied when coefficient modulus with one unknown is greater then sum of modulus coefficient of other unknowns.
