Imagine this scene in performance. How does Tybalt's reaction to Romeo's presence add to the tension in the scene?

The third act in Shakespeare's Romeo and Juliet starts with Tybalt searching for Romeo among his friends, Benvolio and Mercutio. Mercutio is giving Tybalt a difficult time when Romeo approaches them.

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
