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 :-)
