HW Score: $19\mathrm{.}17$:

Points: $0$ of $1$

Solve using Gauss$-$Jordan ellmination.

$3x_1-x_2-5x_3=14$

$x_1-2x_2=8$

Select the correct choice below and fill in the answer box$($es$)$ within your choice.

A$.$ The unique solution is $x_1=x_2=$ and $x_3=$

B$.$ The system has infinitely mant subticet. The solition is $x_1=,x_2=,$ and $x_3=1.$

$$ and $x_3=1.($Simplify your answers. Type expressions using tas the variable.$)$

c$.$ The system has infinitely many solutions. The solution is $x_1=,x_2=s,$ and $x_3=t$

$($Sinplify your answer. Type an expression using s and tas the variables.$)$

D$.$ There is no solution.
