First you expand the brackets:
3x - 27 = 30
And then you can solve:
3x - 27 = 30

3x = 57
÷ 3
x = 19
Hope this helps!

In which is the probability of a sucess, is a value from the Z table and n is the length of the sample.
The upper end is given by:
As n increases, the difference between U and L decreases. This means that the confidence interval gets narrower.
