Let  L =  larger number    and   S = smaller number

L + S  =  17        The sum of the two numbers is 17.

L  =  2 + 2S        The larger number is two more than twice the smaller.

Substitute the value of L from the second equation into the first equation:

(2 + 2S) + S  =  17

2 + 3S  =  17

      3S  =  15

        S  =  5   

        L  =  12
