## Linear System Using Matrices

Linear spaces and subspaces, linear transformations, bases, etc.

### Linear System Using Matrices

Solve the following linear system using matrices:

2x-y+3z=-4
x-2y+z=-1
x-5y+2z+-3

Aug.
2,-1,3 -4
1,-2,1 -1
1,-5,2 -3

I have written the equation into augmented what is next?
help would be very appreciated/

$\left[\begin{array}{ccc|c}
2 & -1 & 3 & -4 \\
1 & -2 & 1 & -1\\
1 & -5 & 2 & -3
\end{array}\right]$

Use Elementary row operations to get the matrix in REF or RREF
