Consider the system of linear equations: $x_1+2x_2+x_3=3$ $2x_1+3x_2+x_3=3$ $3x_1+5x_2+2x_3=1$ The system has |
a unique solution no solution infinite number of solutions exactly three solutions |
no solution |
The correct answer is option (2) : no solution We have, $D=\begin{vmatrix}1 & 2 & 1\\2 & 3 & 1\\3 & 5 & 2\end{vmatrix}=0, $ and $D_1= \begin{vmatrix}3 & 2 & 1\\3 & 3 & 1\\1 & 5 & 2\end{vmatrix}≠0$ So, the given system of equations has no solution. |
