Question

Which explains why Ramone’s equation has no solution?

Answer 1

The matrices must be the same size

Good luck

Answer 2

Answer:

B.The matrix must be of  the same size in order to perform addition or subtraction.

Step-by-step explanation:

We are given that Ramone's wrote the following matrix equation

$A+\left[\begin{array}{ccc}8\\-12\\3\end{array}\right]=\begin{bmatrix}0&18&-21\end{bmatrix}$

We have to explain why Ramone's equation has no solution

$A=-\left[\begin{array}{ccc}8\\-12\\3\end{array}\right]+\begin{bmatrix}0&18&-21\end{bmatrix}$

Using subtraction property of equality

We can not solve because order of I matrix $3\times 1$ and order of second matrix $1\times 3$.

If  the order of two matrix are same then the matrix  will be added or subtract.The  necessary condition for addition or subtraction of matrix is order of matrix should be same.

Hence, option B is true.

Answer:B.The matrix must be of  the same size in order to perform addition or subtraction.
