Solution

As the given matrices are equal, therefore, their corresponding elements must be equal. Comparing the corresponding elements, we get

 xy = 8                                    4 = w

z + 6 = 0                              x + y = 6      

On simplifying, we get
x = 2, y = 4, z = −6, w = 4       or        x = 4, y = 2, z = −6, w = 4

Hence, the values of x, y, z and w is 2, 4, −6, 4 or 4, 2, −6, 4
