Let
x--------> the number of blue beads
y--------> the number of red beads
we know that

-------> equation 
------> equation 
equate equation
and equation 

find the value of x

therefore
the answer is

We are given the following inequality:

If we replace b = 2, we get:

Now we solve for "a" first by subtracting 8 on both sides:

Now we divide both sides by 6

Simplifying:

Therefore, for b = 2, the possible values of "a" are those that are greater than 1/3
