I have a task to calculate a double integral on a region$D=A\setminus B$, where $A=\{(x,y):\text{some system of inequalities}\},B=\{(x,y):\text{another system of inequalities}\}$. What does operator "$\setminus $" mean?

I have a system of linear equations that has no solutions.

It looks like this in augmented matrix form.

$\begin{array}{cccc}1& -1& 2& 5\\ 2& 1& 0& 1\\ 1& 8& -1& 3\\ -1& -5& -12& 41\end{array}$

I need to replace right hand value in equation 4 (41) with a value that will give me a unique solution when in reduced row echelon form. How do I approach this problem in a logical way to find the possible values?
