they have one already solved for m for you, just put that value in for m in the other one

4n=27-3*(11-2n) n = ... If n is that, you can figure m from either equation

4n = 27 - 3 ( 9n)

@DanJS am i right?
DanJS
  • DanJS
no, not sure what you did distribute the 3 into the quantity, then do additions
DanJS
  • DanJS
4n = 27 + (-3)*(11-2n) 4n = 27 - 33 + 6n

n= -30

m i right i solved it through
DanJS
  • DanJS
4n-6n = -6 -2n = -6 n = 3
anonymous
  • anonymous
i added 27 by 33 thats my mistake
DanJS
  • DanJS
you would have to show your steps, not sure what you did
DanJS
  • DanJS
ahh
anonymous
  • anonymous
to find m i sub in 3
DanJS
  • DanJS
yeah distribuiting the quantity gives a - 33
DanJS
  • DanJS
yeah, you know one of the 2 variables, you can use any relationship between the two to figure the other one

  • anonymous
i got m = 5
anonymous
  • anonymous
4 (3) = 27 = 3m 12 = 27 - 3m -15 = -3m m = 5
DanJS
  • DanJS
yes, to check if you are correct, try the value in the other equation , should get the same answer
