Look at my answer to Ulises a few lines down for hint.

Ok, call big one b
call small one s
b = 1 + 2 s
b + s = 3 b  20

from the first equation you know that you can use the quantity (1 + 2 s) for b
so do that
1 + 2 s + s = 3 (1 + 2 s)  20
or
1 + 3 s = 3 + 6 s  20
solve that for s, then go back and find b
