Best ResponseYou've already chosen the best response.0just set up a simple algebra equation. you have one unknown: linda's age. we'll call this x. \[3*x  36 = 2*x\] do you know how to solve from here?

Best ResponseYou've already chosen the best response.0so the trick here is to get all your variables on one side. get the x's on the left and everything else on the right. then combine like terms: 3*x  2*x = 36 1*x = 36 your answer!

Best ResponseYou've already chosen the best response.0@jcntrl: I got 6 as well, and its not working out after I check it, unless Im checking it wrong!

Best ResponseYou've already chosen the best response.0It's a typo on my part. I typed 6 when I'd meant to type 36.

Best ResponseYou've already chosen the best response.0So the steps should be: 3x36=2x 3x2x=36 x(32)=36 x=6/(32) x=6

Best ResponseYou've already chosen the best response.0I know! LOL! Just a corney joke! Ya know what, that's the exact answer I got before, but when i went to check it, it didnt come out right! Could you help me check the answer, please?

Best ResponseYou've already chosen the best response.0What is it that you don't understand? To check the answer, I would go back to the original problem statement and see if my solution holds true. So let's test if my solution of L=36 is true. If three times Linda's age is decreased by 36, the result is twice Linda's age. How old is Linda??? Then is this statement true: 3L36 = 2L 3*3636 = 2*36.............substitute L=36 36(31) = 2*36...............factor 36 out 31 = 2...........................divide both sides by 36 2=2.................................identity. Therefore, the solution is valid.

Best ResponseYou've already chosen the best response.0Sorry, I magically switched from using x as my variable to using L as my variable. It really doesn't mattera duck by any other name is still a duckas long as you can keep it all straight on paper or in your head. :)
