now you need to set up a system of equations to solve
anonymous
  • anonymous
the first one is u+n=18

i got that then i divided it by .2 but it didn't fit
anonymous
  • anonymous
try to turn the sentence-form information they give you into a math equation
anonymous
  • anonymous
divided what by .2? did you understand the idea of a system of equations?
anonymous
  • anonymous
the 18 because it said that had 1/5 as many territories...sorry meant multiplied 18 by .2
anonymous
  • anonymous
basically if you have two variables, you need two equations to work with to solve for the variables

norway has 1/5 as many as the uk.

norway = 1/5 * uk
anonymous

n = 1/5 * u

sorry we just start algebra and the teacher didn't explain this and i couldnt find an example in the book
anonymous
  • anonymous
don't be sorry, it's no problem
anonymous
  • anonymous
now that you have n+u=18 and n=1/5 * u, you want to substitute n back into the first equation so you have only 1 variable to work with
anonymous
  • anonymous
i'm so confused :(
anonymous
  • anonymous
would it be 1/5 * u+u=18 or 2u=18-1/5 or something like that
anonymous
  • anonymous
are you still able to help me
anonymous
  • anonymous
