HOW?

3n - 5 = -8(6 + 5n) 3n-5= -48 - 40n

  • Luigi0210
Like that ^ Thanks you @hello1213
anonymous
  • anonymous
but i don't understand how
anonymous
  • anonymous
3n-5= -8(6) + -8(5n)
anonymous
  • anonymous
okay.. what do i do after that?

get the n numbers together on one side... the other numbers on the other side.
anonymous
  • anonymous
the mission is to isolate n on one side... lets do the right side as the n numbers... what do you get?
anonymous
  • anonymous
actually get the n numbers on the left side it is easier.
anonymous
  • anonymous
i'm confused! can you show me how?
anonymous
  • anonymous
i understand better by seeing how it's done rather than reading
anonymous
  • anonymous
3n-5= -8(6) + -8(5n) 3n-5= -8(6) + -8(5n) <<< multiply 3n-5= -48 + (-40n) now isolate n numbers on left side 3n-5 + 40n= -48 - 40 n + 40n 3n-5+5+40n= -48 + 5 43n = -43
anonymous
  • anonymous
Now what is the answer?
anonymous
  • anonymous
-43?
anonymous
  • anonymous
ohhh i think i get it now
anonymous
  • anonymous

@hello1213 try to avoid doing all of the asker's work for them
anonymous
  • anonymous
nvm i don't get it -_-
anonymous
  • anonymous
-43/43 is what
anonymous
  • anonymous
-1?
anonymous
  • anonymous
43n = -43 to isolate n divide BOTH sides by 43 get it?
anonymous
  • anonymous
ohh yeahh! thanks :)
anonymous
