Solve -{l}{5}{2}+{l}{12}{3}

$$- \left( \begin{array} { l } { 5 } \\ { 2 } \end{array} \right) + \left( \begin{array} { l } { 12 } \\ { 3 } \end{array} \right)$$

Evaluate

$$\left(\begin{matrix}7\\1\end{matrix}\right)$$

Steps Using Rules for Matrix Arithmetic

You can add or subtract two matrices only if both matrices have the same number of rows and columns.

$$\left(\begin{matrix}12\\3\end{matrix}\right)-\left(\begin{matrix}5\\2\end{matrix}\right)$$

To subtract two matrices, subtract the corresponding elements.

$$\left(\begin{matrix}12-5\\3-2\end{matrix}\right)$$

Subtract 5 from 12.

$$\left(\begin{matrix}7\\3-2\end{matrix}\right)$$

Subtract 2 from 3.

$$\left(\begin{matrix}7\\1\end{matrix}\right)$$

Transpose Matrix

$$\left(\begin{matrix}7&1\end{matrix}\right)$$
