x = the smaller number
x + 12 = the larger number
Now, write the equation according to the sentence "the sum of the..." and solve.
x = the smaller number
x + 12 = the larger number

This is how I worked it:
n+12=m
n=m+12
m=5
m=17
n+12=m
n=m+12
m=5
m=17

I don't see how you got the answer from that, unless you guessed and checked. Your answers are correct by plugging them into the sentence.
I would have written this equation and then solved:
x + 2(x+12) = 39
I would have written this equation and then solved:
x + 2(x+12) = 39
