No of sweets with Jennifer = 80
No of sweets with Wendy = 80- x
Jennifer must give half of x i.e x/2 sweets to Wendy so that they have equal no of sweets
If x = 40
No of sweets with Jennifer is 80
No of sweets with Wendy is 80 - x = 80 - 40 = 40
So total no of sweets with both = 80+40 = 120

seersha: Here x/2 came bcz if Jennifer will give x sweets to Wendy then Wendy will have x sweets more
The equation for this is
80 = 80-x
80-x = 80-x+x
80-x = 80
So now Jennifer will have x sweets less than Wendy
If he gives x/2
80-x/2 = 80-x+x/2
80-x/2 = 80-2x/2+x/2
80-x/2 = 80-x/2
Prabhjyotk: thanks for explaining.
