I NEED HELP PLEASE, THANKS! Use Cramer's Rule to find the solution of the system of linear equations, if a unique solution exist

iren2701 [21]

Answer:

Option B

Step-by-step explanation:

We are given the following system of equations -

$\begin{bmatrix}-5x+2y-2z=26\\ 3x+5y+z=-22\\ -3x-5y-2z=21\end{bmatrix}$

Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -

$\begin{bmatrix}-5&2&-2\\ 3&5&1\\ -3&-5&-2\end{bmatrix}$ ,

$\begin{bmatrix}26\\ -22\\ 21\end{bmatrix}$

Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -

$\begin{bmatrix}-5&2&26\\ 3&5&-22\\ -3&-5&21\end{bmatrix}$

Now solve through Cramer's Rule -

x = Dx / D = - 6,

y = Dy / D = - 1,

z = Dz / D = 1

<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>

There would be $13410 because 4500 x 0.22 x 9 = 8910
4500 + 8910 = 13410
