Question

Use Cramer's Rule to solve the system or to determine that the system is inconsistent or contains dependedent equations.
3x+2y=2
6x+5y=1

Answer 1

1 2 1
6 1 5

cover a column take the determinant of whats left, and repeat that process 3 times to get all the needed numbers

Answer 2

D(c1,c2) = Dx
D(c2,c3) = Dy
D(c1,c3) = D

x = Dx/D
y = Dy/D

Answer 3

grrr....

3 2 2
6 1 5

thatll do it , i loathe this tine little laptop

Answer 4

Dy=3(1) - 6(2) = -9
Dx=2(5) - 1(2) = 8
D = 3(5) - 6(2) = 3

y = -9/3
x = 8/3

and dbl chk to make sure :)

Answer 5

thanks
