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
Answer & explanation
Correct answer: option 2
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.
