Miss lees class collected 3 more ball because 21-18 is 3. if i collect 18 balls and my friend collects 21 balls and then we add 21+18 we get 39 and then we put 39 in 13 equal groups we have 3in each group that is why they collected 3.
21-18=3
add 21+18=39
put in equal groups
divide 39 with 3 get thirteen make equal group get 3 in each group
*21-18=3
*21+18=39
*39 divided with 3=13
* 3 in each group
*Answer 3

Remark
You could solve it using logs. Either base will do. They both will give you the same answer (I'll put the second solution before the first one).
Step one
Take the log of both sides.
Log 37^x = log 12
Step Two
Using the power rule for logs, multiply x by the log(37)
x*log(37) = log (12)
Step three
Divide both sides by the log(37)
x = log(12) / log (37)
x = 1.079 / 1.568
x = 0.6882 <<<<< Answer
Use ln
ln 37^x = ln12 Take ln of both sides.
x*ln(37) = ln(12) Multiply x (the power by ln(37)
x = ln(12) / ln(37) Divide by ln(37)
x = 2.485 / 3.611
x = 0.6882
You should be able to put the sentences together just the way I've done it.
