Write the equation that represents this problem:
Kai has 12 more comic books than Parker. If they have 28 comic books altogether, find the number of comic books Kai has. (Make sure you define your variable for full credit)
What is:
x + (x + 12) =28, when x = Parker's comic books or
2x + 12 = 28
x + (x - 12) = 28, when x = Kai's comic books or
2x - 12 = 28
