System of Linear Equations In Exercises 31-40, solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination.
\(\begin{aligned} 2 x_{1}+x_{2}+x_{3}+2 x_{4}=&-1 \\ 5 x_{1}-2 x_{2}+x_{3}-3 x_{4}=& 0 \\ -x_{1}+3 x_{2}+2 x_{3}+2 x_{4}=& 1 \\ 3 x_{1}+2 x_{2}+3 x_{3}-5 x_{4}=& 12 \end{aligned} \)
Text Transcription:
2 x1+x_2+x_3+2 x4=-1
5 x1-2 x2+x3-3 x4= 0
-x1+3 x2+2 x3+2 x4= 1
3 x1+2 x2+3 x3-5 x4= 12
