Let's call the first number  " f "  and the second number  " s " .   We know...

s  =  f - 6

and

s + f  =  12

Plug in   f - 6   for   s   into the second equation.

(f - 6) + f   =   12

2f - 6   =   12

2f   =   18

f   =   9               Use this value for  f  in the first equation to find  s  .

s   =   f - 6   =   9 - 6   =   3
