Question 1022080: charlotte and edgar ages add up to 22 charlotte is one year older than double edgars age how old is charlotte and edgar Found 2 solutions by fractalier, stanbon:Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call Charlotte and Edgar's ages be c and e. Then we have
c + e = 22
c = 2e + 1
Now substitute and get
2e + 1 + e = 22
3e + 1 = 22
3e = 21
e = 7 (Edgar)
so that
c = 15 (Charlotte)
You can put this solution on YOUR website! charlotte and edgar ages add up to 22 charlotte is one year older than double edgars age how old is charlotte and edgar
-----------------------
Equations:

------
Substitute for "c" and solve for "e"::
2e+1 + e = 22
3e = 21
edgar = 7 yrs
