Best ResponseYou've already chosen the best response.1The only thing you have to be very careful is the fact that you are using absolute values in an equation. This makes the problem very likely to have an extraneous solution, so you need to check your answers once you get them.

Best ResponseYou've already chosen the best response.1so if you are interested, try graphing on a calculator as y = 3x2 y = 2x11 you will see two "Vshaped lines" the intersections will give you the answer
