Best ResponseYou've already chosen the best response.0Correct (and I assume you meant x + y = 25).

Best ResponseYou've already chosen the best response.0The easiest way is to group like terms (e.g, terms with x) and then go left to right. For example, in this case they're already grouped: x + 2x + 1 = 25 So we ask ourselves, what is x + 2x?

Best ResponseYou've already chosen the best response.0Right. So then what do you do to bring the 1 to the right?

Best ResponseYou've already chosen the best response.0You have to solve for both. For the first step, you just have to pick one.

Best ResponseYou've already chosen the best response.0I have a hard time with setting it up. sometimes I do X and sometimes it's y

Best ResponseYou've already chosen the best response.0As long as you make sure to keep referring to the same variable as x and y throughout, your result should make sense at the end. You can check it by going out to your very first equation and plugging in your answers and making sure that the numbers on both sides are actually equal.
