# 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
