Sometimes appearances can be deceiving.  However, that is NOT the case here.  Your equation looks completely wrong for the most obvious of reasons; it is completely wrong.  That fact leads us to the very best starting place:  The beginning.





If there are 42 children and  of them are boys, then there are  boys; from which it should be obvious (since  is half of ) that there are 14 girls.

Since there are 28 boys each of whom received  stickers, the total number of stickers received by boys is .  Similarly, the total number of stickers received by girls is .  Then, since the sum of  and  is 1, we can be certain that there were no transgender people in the group of children (hey, you never know these days) so we can make the assertion that the number of stickers given to boys plus the number of stickers given to girls is equal to the total number of stickers given. So:











Solve for  and then calculate
