What is ax + z = aw − y , for a?

Best ResponseYou've already chosen the best response.1You can do the following \[z+y=awax\] notice I added y on both sides and subtracted ax from both sides, now you can factor out an a.

Best ResponseYou've already chosen the best response.1\[z+y=a(wx)\] Notice since the left side both share an a

Best ResponseYou've already chosen the best response.0But how did you get z+y

Astrophysics

Best ResponseYou've already chosen the best response.1Oh I added +y instead of subtracting both sides by z just to make it look cleaner

Best ResponseYou've already chosen the best response.0But is subtracting both sides by z okay

Best ResponseYou've already chosen the best response.1Does that make sense? dw:1444601291806:dw

Best ResponseYou've already chosen the best response.1Yup, that's fine!

Best ResponseYou've already chosen the best response.1With what you did, you should get \[axaw=zy\]

Best ResponseYou've already chosen the best response.0but I got a = yz/xw

Best ResponseYou've already chosen the best response.0it's not a = y+z/xw

Best ResponseYou've already chosen the best response.1\[axaw=zy \implies a(xw) = zy \implies a = \frac{ zy }{ xw }\] that's perfect :)

Astrophysics

Best ResponseYou've already chosen the best response.1\[a = \frac{ zy }{ xw }\] or \[a = \frac{ z+y }{ wx }\] notice if you multiply the first equation by 1 you get the second equation, try to convince yourself by trying it

Best ResponseYou've already chosen the best response.0Do 2 negatives always = a positive in algebra?

Best ResponseYou've already chosen the best response.0Even if they are not side by side

Best ResponseYou've already chosen the best response.0or is it only for variables?

Best ResponseYou've already chosen the best response.1Oh there you're just adding (5+5) = (10) = 10

Astrophysics

Best ResponseYou've already chosen the best response.1Or subtracting by 5 how ever you like

Astrophysics

Best ResponseYou've already chosen the best response.1Unless you mean (5)(5) = 25

Best ResponseYou've already chosen the best response.0but how does yz = a positive?

anonymous

Best ResponseYou've already chosen the best response.0How did you get 1? Was it from factoring the two a's in the equation?

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1Oh no I was trying to show you that the first equation is same as the second, all you have to do is multiply by 1, algebra doesn't care :P So the way I did your problem was basically the same way except I moved things differently, dw:1444602003999:dw

Best ResponseYou've already chosen the best response.0so it could come out either way and be right?
