In this problem, we have been given some matrices and it is said that a plus b is equal to c.
00:07
We need to use this to find the values of the scalar constants a, b, c, and d.
00:11
So what is the matrix a? matrix a is negative 2, 3, 1a.
00:18
With this, we add the matrix b, which is b, negative 1, 2, negative 4.
00:24
And this is given to be equal to the matrix c, which is 1c, d, 4.
00:31
So on the left -hand side, let's add these two mattresses, which we do by adding the corresponding elements.
00:37
So we end up with negative 2 plus b.
00:39
Here we have 3 plus negative 1.
00:42
Then we have 1 plus 2.
00:44
Here we have a plus negative 4.
00:47
So this is equal to 1cd4.
00:52
So let's simplify these...
