Answer:
9 ... 3
9 ... 7
Step-by-step explanation:
Given
Matrices A and B
Let A ,=
5 2
3 0
And B =
4 1
6 7
Two matrices must have an equal number of rows and columns to be added.
As seen above, the two matrices have 2 rows and 2 columns, so they can be added together
To as these two matrices, we add corresponding rows and columns only.
Take for instance, matric A is represented by
a11 .. a12
a21 .. a22
And
Matric B is represented by
b11 .. b12
b21 .. b22
Their sum can be represented as follows
a11 + b11 .. a12 + b12
a21 + b21 .. a22 + b22.
So, the result of the question, using the above illustration is
a = 5+ 4
b = 2 + 1
c = 3 + 6
d = 0 + 7
So, the matrix becomes
9 ... 3
9 ... 7
