The denominator of a fraction is 2, more than twice the numerator. If 7 is added to both the numerator and the denominator the new fraction would be equivalent to 2/3. Determine fhe original fraction.

OK, so lets call the numerator n. The denominator is 7 more than twice the numerator. Put into an equation, it would look like this.
n/2n+7
You add 7 to both, and it will look like this:
n+7/2n+14
You should be able to solve from here.
Cheers!
