Linear algebra number 14 and 16 1.1 

# Solving Systems of Linear Equations

### Solve the systems in Exercises 11–14:

**11.**
\[ 
\begin{aligned}
&x_2 + 5x_3 = -4 \\
&x_1 + 4x_2 + x_3 = -2 \\
&2x_1 + 7x_2 + x_3 = -2 
\end{aligned}
\]

**12.**
\[ 
\begin{aligned}
&x_1 - 5x_2 + 4x_3 = -3 \\
&2x_1 - 7x_2 + 3x_3 = -2 \\
&-2x_1 + x_2 + 7x_3 = -1 
\end{aligned}
\]

**13.**
\[ 
\begin{aligned}
&x_1 - 3x_3 = 8 \\
&2x_1 + 2x_2 + 9x_3 = 7 \\
&x_2 + 5x_3 = 2 
\end{aligned}
\]

**14.**
\[ 
\begin{aligned}
&2x_1 = 6x_3 = -8 \\
&x_2 = x_3 = 3 \\
&3x_1 + 6x_2 = 2x_3 = 9 
\end{aligned}
\]

---

**15. Determine if the systems in Exercises 15 and 16 are consistent. Do not completely solve the systems.**

\[ 
\begin{aligned}
&x_1 + 6x_2 = 5 \\
&2x_2 + 4x_3 - x_4 = 0 \\
&-x_1 + 6x_2 + 5x_3 = 3 \\
&x_2 + 5x_3 + x_4 = 0
\end{aligned}
\]

**16.**
\[ 
\begin{aligned}
&2x_1 + 4x_4 = -10 \\
&3x_2 + 3x_3 = 0 \\
&4x_1 + 4x_4 = 1 \\
&3x_1 + 2x_1 + 3x_1
