Question 109914
Let x=number of votes for the loser

Then x+220=number of votes for the winner

Now we are told that:
 loser votes + winner votes=810.  So our equation to solve is:

x+x+220=810  subtract 220 from both sides
x+x+220-220=810-220  collect like terms

2x=590  divide both sides by 2

x=295---------------------------------number of votes for loser

x+220=295+220=515----------------------number of votes for winner

CK

295+515=810
810=810
and
295+220=515
515=515
