Answer:

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Step-by-step explanation:

You can use these Cramer's formulas to solve for x and y:

$x=\dfrac{|A_x|}{|A|},\\ \\y=\dfrac{|A_y|}{|A|},$

where

$|A|=\left|\begin{array}{cc}12&-13\\ \\17&-22\end{array}\right|\\ \\ \\|A_x|=\left|\begin{array}{cc}7&-13\\ \\-51&-22\end{array}\right|\\ \\ \\|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

So,

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Distribute and combine like terms.<br> 7(4a+3b-6)-3(3a-2b+4)

andrew11 [14]

Answer:

19a+27b-54

Step-by-step explanation:

First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.

28a+21b-42

Then do the same for -3 and (3a-2b+4).

-9a+6b-12

Rewrite the equation 28a+21b-42-9a+6b-12.

Combine like terms: 19a+27b-54
