Alex is 16 years old and his sister Ramie is 5 years old. In how many years will Alex be exactly twice as old as Ramie?
A)8 years B)6 years C)5 years D)10 years
Let number of years for Alex to be twice Ramie's age, be y
We then get: 16 + y = 2(5 + y)
16 + y = 10 + 2y
y - 2y = 10 - 16
- y = - 6
y, or Number of years for Alex to be twice Ramie's age = %28-+6%29%2F%28-+1%29, or highlight_green%286%29
