The three Math Idol judges have been eliminating contestants all day! The number of onestep equations and twostep equations who have been eliminated today is equal to 1070! If three times the number of onestep equations minus twice the number of twostep equations is equal to 110, how many onestep equations auditioned today?
900

Best ResponseYou've already chosen the best response.1This answer will only tell you the number of onestep equations that have been eliminated. We don't actually know how many auditioned. Also, be careful with the use of ! in mathematics as 1070! = 1070 x 1069 x 1068 x.......x 3 x 2 x1 Let A be the number of onestep equations eliminated and B the number of twostep equations eliminated then, A + B = 1070 .....Equation (1) and we are told that, 3A  2B = 110.....Equation (2) multiplying Eqn (1) by 2 gives 2A + 2B = 2140........now add Eqn(2) 3A  2B = 110 5A = 2250 ⇒ A = 450....which is the number of onestep equations ELIMINATED today.
