Answer:

\left[\begin{array}{ccc}-5&6\\1&-4\end{array}\right]

Step-by-step explanation:

To find the product of two matrices we need to multiply the elements of each row of the first matrix by the elements of each column in the second matrix. Then we should add the products. Then:

\left[\begin{array}{ccc}-3&4\\2&-5\end{array}\right] × \left[\begin{array}{ccc}3&-2\\1&0\end{array}\right] = \left[\begin{array}{ccc}-9+4&6+0\\6-5&-4+0\end{array}\right] = \left[\begin{array}{ccc}-5&6\\1&-4\end{array}\right]

The solution is \left[\begin{array}{ccc}-5&6\\1&-4\end{array}\right]

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19       <em>add 29 to both sides</em>

10y = 7y + 48          <em>subtract 7y from both sides</em>

3y = 48      <em>divide both sides by 3</em>

y = 16



3x + 7 = 5x - 21            <em>subtract 7 from both sides</em>

3x = 5x = -28         <em>subtract 5x from both sides</em>

-2x = -28     <em>divide both sides by (-2)</em>

x = 14
