Find the values o

Since, the given matrices are equal, their corresponding elements are also equal.

Comparing the corresponding element, we have:

x + y + z = 9...(1)

x + z = 5.....(2)

y + z = 7.......(3)

Putting the value of equation 2 in equation 1,

y + 5 = 9

⇒ y = 4

Then, putting the value of y in equation 3, we get,

4 + z = 7

⇒ z = 3

Therefore, x + z = 5

⇒ x = 2

Therefore, x =2, y = 4 and z = 3.
