Amy, Jeremy, and Chris have a combined age of 132.  Amy is 1/3 the age of Jeremy, and Chris is twice as old as Amy.  How old is Jeremy?
Define a variable ** Let x represent the age of Jeremy
How old is Amy? ** Amy:(1/3)x
How old is Chris? ** Chris:2(1/3)x=(2/3)x
Write an equation ** Total:x+(1/3)x+(2/3)x=132
Combine like terms ** 2x=132
Divide by 2 ** x=66 years old
#### 66
