Solve using augmented matrix methods.
\[
\begin{array}{l}
-4 x_{1}-2 x_{2}=3 \\
-8 x_{1}-4 x_{2}=2
\end{array}
\]
Select the correct choice below and fill in any answer boxes in your choice.
A. The unique solution is \( x_{1}= \) and \( x_{2}= \) (Simplify your answer.)
B. The system has infinitely many solutions. The solution is \( x_{1}=\square \) and \( x_{2}=t \) (Simplify your answer. Type an expression using \( t \) as the variable)
C. There is no solution.
