Answer:

The value of x fro the given matrixes equation is [tex]\begin{bmatrix}- 15&  - 6 & - 9 & 1\end{bmatrix}[/tex]  

Step-by-step explanation:

Given matrixes equation as :

A + 2 x = 3 B

Where A = [tex]\begin{bmatrix}- 3 & 12 & - 3 & 8\end{bmatrix}[/tex]

B =  [tex]\begin{bmatrix}- 11& 0 & - 5 & - 2\end{bmatrix}[/tex]

So ,

[tex]\begin{bmatrix}- 3 & 12 & - 3 & 8\end{bmatrix}[/tex] + 2 x = 3  [tex]\begin{bmatrix}- 11& 0 & - 5 & - 2\end{bmatrix}[/tex]

Or, 2 x = [tex]\begin{bmatrix}- 33& 0 & - 15 & - 6\end{bmatrix}[/tex] - [tex]\begin{bmatrix}- 3 & 12 & - 3 & 8\end{bmatrix}[/tex]

Or,  2 x = [tex]\begin{bmatrix}- 33& 0 & - 15 & - 6\end{bmatrix}[/tex] + [tex]\begin{bmatrix} 3 &- 12 &  3 & - 8\end{bmatrix}[/tex]

Or, 2 x =  [tex]\begin{bmatrix}- 33 + 3& 0 - 12 & - 15 - 3 & - 6 + 8\end{bmatrix}[/tex]

Or , 2 x =  [tex]\begin{bmatrix}- 30&  - 12 & - 18 & 2\end{bmatrix}[/tex]

Or, x = [tex]\frac{\begin{bmatrix}- 30 & - 12 & - 18 & 2\end{bmatrix}}{2}[/tex]

∴   x =  [tex]\begin{bmatrix}- 15&  - 6 & - 9 & 1\end{bmatrix}[/tex]

Hence The value of x fro the given matrixes equation is [tex]\begin{bmatrix}- 15&  - 6 & - 9 & 1\end{bmatrix}[/tex]    Answer
