Answer:
Not possible.
Step-by-step explanation:
Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.
Order of a matrix with rows and
columns is
.
Here, matrix A is
Matrix B is .
Multiplying a matrix by a constant doesn't change its order.
So, order of matrix A is as it has 3 rows and 2 columns.
The order of matrix 3B is as it has 2 rows and 3 columns.
Therefore, addition is not possible as the order is different.

Answer:
divide by x
Step-by-step explanation:
To answer your question, you can get from A to B by dividing by x:
However, this is only a valid operation if x ≠ 0. In this equation, x = 0, so that division is not valid.
__
A better approach to the solution is to put the equation in standard form:
f(x) = 0
You can get there by subtracting 3x from both sides.
5x -3x = 3x -3x
2x = 0
Now, you can legitimately divide by 2 to find ...
x = 0 . . . . . . . . the reason why dividing by x is not allowed
