3x+4=6x+19 subtract 3x from both sides
4=3x+19 subtract 19 from both sides
-15=3x divide by 3 on both sides
-5=x

Answer:

The products of AB and BA is given by

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$

Step-by-step explanation:

Given the matrices A= $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right]$ and

B= $\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right]$

To find the product AB and BA

AB= $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right] \left[\begin{array}{cc}1 & -1\\-3 &0\end{array}\right]$

$=\left[\begin{array}{cc}6+15& -6+0\\-3+12&3-0\end{array}\right]$

Therefore the product of AB is

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right]$ $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right]$

$=\left[\begin{array}{cc}6+3& -5+4\\-18+0&15+0\end{array}\right]$

Therefore the product of BA is

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$

The products of AB and BA is given by

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$
