I dont understand how she (my teacher) got rid of the 5x1

Do it:

  1. R3 = R3 - 5R1
  2. R3 = R3 - 5R2
#

It does not lead you to the same, but for that matter you show that the system is consistent

$R_2 \leftarrow \frac{1}{2}R_2$ \
$R_3 \leftarrow \frac{1}{8} (\frac{1}{5}R_3 - R_1 - 2R_2)$

The steps for $R_3$ are : \
$R_3 \leftarrow \frac{1}{5} R_3$ \
$R_3 \leftarrow R_3 - R_1$ \
$R_3 \leftarrow R_3 - 2R_2$ \
$R_3 \leftarrow \frac{1}{8}R_3$
