In a random sample of 100 Americans of voting age, 10 more Americans identify themselves as Independents than Republicans. Six fewer Americans identify themselves as Republicans than Democrats. Assuming that all of those sampled are Republican, Democrat, or Indepenent, how many of those in the sample identify themselves with each political affiliation?
I have to put this into a system of equation. Is this the right way to set it up into a system of equations? This is what I came up with.
r = i+10
d = r - 6
d + r + i = 100
