Solution 1

Why do you think multiplication operation can always be inverted?! You got a singular matrix, just face it. It cannot be used as a denominator in matrix division or inversion. This is the same thing as deleting by integer 0.

Please see:

Solution 2

Non-square matrices (m-by-n matrices for which m not equal to n) do not have an inverse.
Thus singular matrix can't be inverted
