Need some help with this matrices question​

Mathematics

Answer:

4. D

5. D

Step-by-step explanation:

To subtract Matrices, subtract the numbers that are in the same position.

You can only add or subtract Matrices that have the same order.

Here, both Matrix X and Y, are 2 by 2 matrices.

So let's subtract

5 - 6 =   - 1

- 4 - ( - 1) =  - 3

3 - ( - 7) = 10

- 2 - 4 =  - 6

The Matrix that matches that is D so the answer to 4 is D.

5. We do the same thing above, but we multiply by 2 first.

5 - 2(6 ) =  - 7

- 4 - 2( - 1) =  - 2

3 - 2( - 7) = 17

- 2 - 2( 4) =  - 10

The answer here is D as well.
