Find x, y and z s

Answer :

Given two matrices are equal as A = B.


We know that if two matrices are equal then the elements of each matrices are also equal.


x – 2 = y …… (1)


z = 3


And y + 2 = z …… (2)


2y = 6z


y = 3z ……(3)


Putting the value of z in equation (3)


y = 3z = 3×3 = 9


Putting the value of y in equation (1)


x – 2 = 9


x – 2 = 9


x = 9 + 2


x = 11


x = 11, y = 9, z = 3
