Ahmed is 11 years old and Fouad is 26 years old. In how many years will Fouad's age be double Ahmed's current age?
Thoughts? Step-by-step reasoning:
Let X be the number of years before Fouad's age doubles Ahmed's age. So (X + 11) * 2 = X + 26. So X * 2 + 22 = X + 26. So X = 26 - 22 = 4 years.
Thus, the answer is 4.
