Question 403164: Hello,
I am trying to understand what is required of me in the following two math problems.
1. Modify the second row in the following matrix by adding first row to the second.
2 3 4
-2 1 0
1 3 5
Here is my solution.
(2 + -2) (3+1) (4+0) = 0 4 4
Which makes the final answer,
2 3 4
0 4 4
1 3 5
2. Modify the third row of the following matrix by adding the first row to the third.
1 2 -1
4 1 3
2 1 4
Here is my solution.
(1+2) (2+1) (-1+4) = 3 3 3
Which makes the final answer,
1 2 -1
4 1 3
3 3 3
Is this the correct way to do these problems?
Thank you for any help.
