Best ResponseYou've already chosen the best response.2@headge  Do you understand negative numbers? So, in this example it's okay for the answer to be less than zero, or rewrite it as @Agent47 has done.

Best ResponseYou've already chosen the best response.0To answer your question, you need to simplify the issue. You need to put y/40 outside the brackets and the remaining numbers inside the brackets. Then you will see that 2057 is definitely not the same value as 5720

Best ResponseYou've already chosen the best response.2Now *that's* an excellent example there @MarkRijckenberg @headge  I'd be careful about how I interact with the people who are helping you, ok? Now, what part of this problem don't you understand? Did Mark's example help?

Best ResponseYou've already chosen the best response.0Y/2  5y/8 + 4y/5 = 20y/40  25y/40 + 32y/40 = 20y/40  57y/40 Then I got stuck. What do you mean? What have I said that is rude?

Best ResponseYou've already chosen the best response.2Hmm, so now I'm confused. Are you supposed to solve for y in this problem? In terms of your original question, are you able to do that part? 20  57 = ?

Best ResponseYou've already chosen the best response.2Ok, understood. So, are you able to subtract 20y from 57y? An easier way to think of it is by adding a negative, as @Agent47 did. So, 57 + 20 = ? (this answer will be a negative number FYI)

Best ResponseYou've already chosen the best response.0I disagree: Y/2  5y/8 + 4y/5 = 20y/40  25y/40 + 32y/40 = 5y/40 + 32y/40 = 27y/40
