Claire's cousin is now 3 times as old as Claire. In 10 years, her cousin will be twice as old as Claire. How old is Claire now?
~~~~~~~~~~~~~~
Clara = x years old
The cousin is 3x years old now.
In 10 years
3x + 10 = 2*(x+10)
Simplify and solve
3x + 10 = 2x + 20
3x - 2x = 20 - 10
x = 10.
ANSWER. Clara is 10 years old now.
