First one is A:=

\(\displaystyle X_1-X_2 \leq 1\)

\(\displaystyle X_1 \leq3\)

\(\displaystyle X_2 \geq 1\)

\(\displaystyle X_1,X_2 \geq 0\)

Second one is B:=

\(\displaystyle X_1+X_2 \geq 5\)

\(\displaystyle X_1\leq5\)

\(\displaystyle X_1\geq4\)

\(\displaystyle X_2\leq4\)

\(\displaystyle X_1,X_2 \geq 0\)

I had like to write it as a set \(\displaystyle C := A\oplus B\), with C made of linear inequations too. I'm not so sure of how to tackle such problem, if anyone can help!
