Best ResponseYou've already chosen the best response.2128 = 2^7 So, 2^(x+3y) = 128 2^(x+3y) = 2^7 Since the bases on both sides are the same, you can equate the power x+3y = 7 < This is equation 1 2^(3x–y) = 2 2^(3x–y) = 2^1 Since the bases on both sides are the same, you can equate the power 3xy = 1 < this is equation 2 You have two equations and two unknowns. You can solve them now.
