Find the values o

Answer :

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.
