Can you find a number such that...
...its double is fourteen more than its quarter?

The number is less than 20.
We need a number (N) such that:
2 x N = 14 + N
Multiply throughout by 4 to give:
8 x N = 56 + N
7 x N = 56
So N = 8.
It's double is 16.
It's quarter is 2.
So its double is fourteen more than its quarter.
