1.5.20 Systems of algebraic equations
Condition: Using the Jordan-Gauss method, investigate the compatibility of the system of equations and, if it is consistent, then find its solution. If the system is uncertain, then find two general and corresponding basic solutions. \[ \left\{\begin{array}{c} 3 x_{1}+4 x_{2}+3 x_{3}+10 x_{4}+17 x_{5}=20 \\ 3 x_{1}+5 x_{2}+3 x_{3}+11 x_{4}+19 x_{5}=22 \\ 6 x_{1}+8 x_{2}+x_{3}+15 x_{4}+24 x_{5}=25 \end{array}\right. \]
Solving systems of algebraic equations by the methods of Gauss, Jordan-Gauss, Cramer and using the inverse matrix. Homogeneous and non-homogeneous systems of equations.
