Question 28341: Caitlin is 21 years old, which is 6 less then 3 times Kims age. Which equaition could be used to slove for Kims age? How old is kim? Answer by emmychan(11) (Show Source):
You can put this solution on YOUR website! Use y for Kim's age and x for Caitlin's.

3y = 27
Divide both sides by 3.
y = 9
