If find x, y, z, ω.

Given two matrices are equal.


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


x = 3 …… (1)


And 3x – y = 2 …… (2)


And 2x + z = 4 …… (3)


3y – ω = 7 …… (4)


Putting the value of x in equation (2)


3×3 – y = 2


9 – y = 2


y = 9 – 2


y = 7


Now, putting the value of y in equation (4)


3×7 – ω = 7


21 – ω = 7


ω = 21 – 7


ω = 14


Again, Putting the value of x in equation (3)


2×3 + z = 4


6 + z = 4


z = 4 – 6


z = – 2


x = 3, y = 7, z = – 2 and ω = 14
