Greg is 3 years older than kevin. in seven years, the sum of their ages will be 41. how old is each now ?

Let their ages be g and k.  Then g = k + 3.

Next:  (g+7) + (k+7) = 41.

Substituting k + 3 for g in the above equation, we get  k + 3 + 7 + k + 7 = 41.

Combining like terms:  2k + 17 = 41.  Then 2k = 24, and k = 12.

Kevin is 12 years old and Greg is 15 years.
