IDZ Ryabushko 1.2 Option 9

No. 1. If you need to solve a system of equations, you first need to determine its compatibility. If the system is consistent, then it can be solved in different ways: a) using Cramer’s formula; b) using an inverse matrix; c) Gaussian method.

No. 2. If you need to solve a system of equations, then the first step is to check its compatibility. If the system is consistent, then it can be solved in several ways: a) using Cramer’s formula; b) using the inverse matrix; c) Gaussian method.

No. 3. To solve a homogeneous system of linear algebraic equations, you need to apply the Gauss method. First, it is necessary to bring the system matrix to a stepwise form, and then bring it to an improved stepwise form. The resulting matrix must be rewritten as a system of equations and all variables must be expressed in terms of free variables.

No. 4. To solve a homogeneous system of linear algebraic equations, you can use the Gauss method. First you need to bring the system matrix to a stepped form, and then to an improved stepped form. The resulting matrix should be rewritten as a system of equations and all variables should be expressed in terms of free variables.
