In helping my daughter check some homework, I was using a 48gii to solve systems of 2 equations with 2 unknowns.

This one obviously has no solution but the 48gii says it does:

\[8x+4y=-5 \\

8x+4y=12\]

The 48gii says the answer is

\[ \begin{bmatrix} 0.35\\ 0.175 \end{bmatrix} \]

Even my 35s says NO SOLUTION :-)
