If everyone is a bear,
Let number of bear = X
Each bear has 2 eyes,
Hence, total number of eyes = X x 2 = 2X
There's a saying, an eye for an eye.
A bull also has 2 eyes.
Number of bull's eyes is equivalent to the number of bears' eyes.
However, i play darts just now and got 6 bulls' eyes.
Which makes our total number of bulls' eye = 2X + 6
Since you want to know how many bulls are there,
all we need to do, is to divide our sum " 2X + 6" into 2, and we will get the number of bull.
The answer is X + 3,
I think you should change the question to :
How many bears are there?
in order to find X, and ultimately, you will get the answer on how many bulls are there.
Cheers
