You can  put this solution on YOUR website! let the first number be called "a", and the second "b".
 
from the question, we can tell that a-b=20............. eqn 1 
 
also from the question,
 
b goes into a 2 times, with 5 left over. This tells us: 2b+5=a.......... eqn 2
 
Now if we replace a in the first equation withe equation 2, we get
 
2b+5-b=20 
and rearranging: 
b+5=20 
b=15
 
Now we can replace the b in equation 2 with the number 15: 
2(15)+5=1 
30+5=a 
a=35
