Anna is 6 and her mother is 34. How long will it be before her mother is twice as old as she is?
---
The difference is 34-6 = 28
----
Equation:
Let "x" be the required difference.
Solve: 34+x = 2(6+x)
34+x = 12+2x
x = 22
In 22 yrs, mother will be twice as old as Anna.
----
Checking:
6+22 = 28:::::Anna's future age
---
34+22 = 56::::Mother's future age
