Question

5x - 3y= 1 and 6x-y = 9 solvw by cramer rule​

Answer 1

Answer:

Step-by-step explanation:

6x - 9 = y

5x - 3( 6x - 9 ) = 1

5x - 18x + 27 = 1

- 13x  = 1 - 27

-13x = - 26

x = 2

6 ( 2) - 9 = y

12 - 9 = y

3 = y

Answer 2

Hello !!

For you answer this question, you only need make use of this method below. See the resolution.

Find D.

$\left(\begin{array}{cc}5&-3\\6&-1\end{array}\right)$

__________________

D = -5 - (-18)

D = -5 + 18

D = 13

Find Dx.

$\left(\begin{array}{cc}1&-3\\9&-1\end{array}\right)$

___________________

Dx = -1 - (-27)

Dx = -1 + 27

Dx = 26

Find Dy.

$\left(\begin{array}{cc}5&1\\6&9\end{array}\right)$

__________________

Dy = 45 - 6

Dy = 39

The solution for (x).

x = (Dx/D) = 26/13 = 2

The solution for (y).

y = (Dy/D) = 39/13 = 3

Final result : the solution for (x) is 2 and the solution for (y) is 3.

I hope I have collaborated !
