Question
If A = 2543 and 2A + B is a null matrix, then B is equal to :
Solution
The question seems to be incomplete. In order to solve this, we need to know the dimensions of the matrix A and the matrix B. However, if we assume that A is a scalar and B is a matrix, then the problem can be solved as follows:
Given that A = 2543 and 2A + B is a null matrix, we can write the equation as:
2A + B = 0
We can rearrange this equation to solve for B:
B = -2A
Substituting the given value of A into this equation gives:
B = -2 * 2543 = -5086
So, if A is a scalar and B is a matrix, then B is a matrix where all elements are -5086. However, without additional information about the dimensions of the matrices, this is the best answer that can be provided.
