Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)

Step-by-step explanation:
3.5% of listeners rated the song as 1 star
49 listeners rated the song as 1 star
49 listeners = 3.5% of listeners
we want to find 100% of listeners. we can do this by multiplying both sides of the equation by 100/3.5, getting one side to 100% and the other to what it is equal to
49 * 100/3.5 listeners = 100% of listeners = 1400
