# For what value of

Given two matrices are equal .i.e, A = B.

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

2x + 1 = x + 3

2x – x = 3 – 1

x = 2 ……(1)

And 2y = y2 + 2

y2 – 2y + 2 = 0

(No real solutions) …… (2)

And y2 – 5y = – 6

y2 – 5y + 6 = 0

y2 – 3y – 2y + 6 = 0

y(y – 3) – 2(y – 3) = 0

(y – 3)(y – 2) = 0

y = 3 or 2 …… (3)

From the above equations we can say that A and B can’t be equal for any value of y.
