How does Shakespeare structure his play​

A shakespearean tragedy traditionally follows the Freytag pyramid of Dramatic structure which consists of five parts. Freytag's analysis is derived from Aristotle's poetics that had a three-part view of a plot structure. the five parts are: Exposition, Rising Action, Climax, Falling Action and Denouement.

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

answer: x = 4 and y = 4
