 Question 549381: under what conditions it has been following matrix equality? ( x y) * (1 1) = (1 1) * (x y) ( z w) (0 1) .... (0 1) (z w) Answer: provided that z = 0 and x = w How? Thank youAnswer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!under what conditions it has been following matrix equality? ( x y) * (1 1) = (1 1) * (x y) ( z w) * (0 1) = (0 1) * (z w) Answer: provided that z = 0 and x = w How? --- Equations: x + 0*y = x + z x + y = y + w z + 0*w = z + w z + w = 0y + w -------------------- From the 2nd row: x = w From the 4th row: z = 0 =============================== Cheers, Stan H.
