Question

Matrice help please?

Answer 1

`\mathbf X=\begin{bmatrix}-\frac43&-5\\\\-2&-\frac14\end{bmatrix}`

`\mathbf Y=\begin{bmatrix}-\frac23&6\\\\4&-\frac34\end{bmatrix}`


`\mathbf Y+\mathbf X=\begin{bmatrix}-\frac23-\frac43&6-5\\\\4-2&-\frac34-\frac14\end{bmatrix}=\begin{bmatrix}-2&1\\2&-1\end{bmatrix}`


`4(\mathbf Y+\mathbf X)=\begin{bmatrix}4(-2)&4(1)\\4(2)&4(-1)\end{bmatrix}=\begin{bmatrix}-8&4\\8&-4\end{bmatrix}`

`\mathbf M=\begin{bmatrix}2&-1\\-3&0\\5&2\end{bmatrix}`

`\mathbf N=\begin{bmatrix}1&-4&7\\3&-1&1\end{bmatrix}`
