Write a 500 word argumentative essay on the following topic. There are many people who believe that schools should impose a dress code on their students. This ensures equality amongst students avoids gang membership and fashion shows on school campuses. Others believe that this means no individuality or student freedom. Support or reject this argument.

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

true
