QUESTION 2
Fill in the blanks.
Given the system of equations:
$4x_1 - 2x_2 + 2x_3 = 10$
$2x_1 + x_3 = 3$
$4x_1 + x_2 + 4x_3 = 6$
And recalling Cramer's Rule (pg 298)
$x_1 = \frac{D_1}{D}, x_2 = \frac{D_2}{D}, x_3 = \frac{D_3}{D}$
$D = \underline{\qquad\qquad\qquad}, D_1 = \underline{\qquad\qquad\qquad}, D_2 = \underline{\qquad\qquad\qquad}, D_3 = \underline{\qquad\qquad\qquad}, x_1 = \underline{\qquad\qquad\qquad}$

QUESTION 2
Fill in the blanks.
Given the system of equations:
4x1 - 2x2 + 2x3 = 10
2x1 + x3 = 3
4x1 + x2 + 4x3 = 6
And recalling Cramer's Rule (pg 298)
x1 = (D1)/(D), x2 = (D2)/(D), x3 = (D3)/(D)
D = , D1 = , D2 = , D3 = , x1 =
