On April 19, 1775, a group of American farmers serving as Minute Men began the American
Revolution when they fired at the British at Lexington and Concord, Massachusetts. Some
decades later, Ralph Waldo Emerson called the first shot of the Revolution "the shot heard
round the world." Emerson used the phrase in his "Concord Hymn," which was sung on April
19, 1836, at the unveiling of a monument honoring the Minute Men's stand.

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

Delegates: representatives who cast votes at a political party's national convention. binding: if a primary or caucus is “binding” that means the delegates won in that contest are legally bound to vote for a particular candidate at the parties national convention.a primary is a preliminary election used to determine a party's nominee for a specific office. the winner of the party's caucus, or primary, wins the party nomination for that state. then the delegates meet at their party's national party convention, which is a formal gathering of all party delegates from all states.
