2 x 2 Solve = 48gii Fail - ndzied1 - 04-24-2014 03:43 AM
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 :-)

The 50g gives the same result as the 48 (a 48GX in my case).
My 42S gives a result of [ -8.5E12 1.7E13 ]
The Prime, like the 35s, returns "No solutions"

Maybe stating the obvious - BUT -
NO Solution is interpreted as no Intersection solution as they are Parallel Lines.
