Homework Equations
5 2
0 -4 _X_ 3 7
1 6 ___ -2 0
The Attempt at a Solution
The answer I got was
18 42
-8 0
Can one of you intellectuals tell me if I got the right answer?
EDIT: I realized I didn't actually tell you what I did. I took the first column of numbers in the first matrix (5, 0, 1), and added together the products of it and the first number in the first column (3). I took the 3 numbers from the second column (2, -4, 6) and added the products of them and the first number in the second column (7). I repeated that with the -2 and the 0.
