Answer with Step-by-step explanation:
Since we have given that

As we know that
AA⁻¹ = I (A is invertible matrix)
Multiplying A⁻¹ on the both the sides:

Using the above result, we get that

Therefore, BA = AB
Hence, proved.
X = 1 and y = 2
Hope this helps :)
I am sure about it. I am not good at making all the signs that's why did not show the steps but still I am right.

Answer:
-25 ≠ 21
Step-by-step explanation:
it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)
you would substitute -5 for x and 3 for y in the equation
5(-5) = 4(3) + 9
-25 = 12 + 9
-25 = 21
the question is asking you to see if the left side is equal to the right side of the equation
-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
