Washington tells Hamilton, let me tell you what I wish I'd known, when I was young and dreamed of glory! You have no control who lives, who dies, who tells your story
What does he mean by this?

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
