Question

Explain why this matrix equation has no solution: A + 11 17 −8 13 = 0 0 0 0

Answer 1

Sample Response – The two matrices are different sizes. It is not possible to add matrices with different sizes.

Answer 2

If you mean

`A+\left[\begin{array}{cccc}11&17&-8&13\end{array}\right]=\left[\begin{array}{cccc}0&0&0&0\end{array}\right]`

there is a solution and it is the opposite of the matrix constant on the left.

`A=\left[\begin{array}{cccc}-11&-17&8&-13\end{array}\right]`

Adding anything with its opposite gives zero.
