How does faulkner tell a story from different angles in as i lay dying?

a. by employing a narrator who has split personality disorder
b. by using addie's point of view both before and after dying
c. by having more than one character tell the same story
d. by telling the story through an unbiased, all-knowing character

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

is it rising action, falling action, climax, or resolution? need answer also
