(Solved): Solve using Gauss-Jordan elimination. 4x1+4x211x3=253x1+17x246x3=34x1 ...

Solve using Gauss-Jordan elimination. $$\begin{array}{r}4x_1+4x_2?11x_3=?25\\ 3x_1+17x_2?46x_3=?34\\ x_1+3x_2?8x_3=?8\end{array}$$ Write the system of equations as an augmented matrix. Solve the system. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. The unique solution is $$x_1=,x_2=$$, and $$x_3$$ (Simplify your answers.) B. The system has infinitely many solutions. The solution is $$x_1=,x_2=$$, and $$x_3=t$$. (Simplify your answers. Type expressions using $$t$$ as the variable.) C. The system has infinitely many solutions. The solution is $$x_1=,x_2=s$$, and $$x_3=t$$.
