Best ResponseYou've already chosen the best response.0well first of all you would have to solve for x and then figure out the answer to 3(x + 3y + 2x − y ) in order to get your answer ;)

Best ResponseYou've already chosen the best response.0am going to do this using substitution and then by elimination. SUBSTITUTION METHOD Let's solve the first one in terms of y. y = 3x. Plug 3x where you see y in the second equation. 2x  3(3x) = 16 2x  9 +3x = 16 5x 9 = 16 5x = 25 x = 5 Plug x=5 back into the other equation. 2(5)  3y = 16 10  3y = 16 3y = 6 y = 2 So our solution is (5,2) or x=5y=2
