\begin{pmatrix}
1 & 1 & 5 & 1 \
0 & -1 & -2 & -2 \
0 & 0 & 0 & 5
\end{pmatrix}

can someone check if this is a valid REF to this matrix/ and then how do I get it into RREF? Pls help really lost, I just used Gauss Method to eliminate x terms with R1 then y terms with R2; is there any process or steps to convert to RREF?
