Hi there! The answer is A. x = 12
The angles (taken together) are complementary angles: the sum of the angles is 90 degrees. When we know this, we can set up and solve an equation.
(3x + 6) + 48 = 90
Work out the parenthesis
3x + 6 + 48 = 90
Collect terms
3x + 54 = 90
Subtract 54
3x = 36
Divide by 3
x = 36 / 3 = 12
Therefore, the solution for x, gives x = 12. A is the correct answer.

Alright! In order to solve this you have to work backwards. So, you know her end total is 36. And to get to that she bought 16 books. So:
36 - 16 = 20.
So, after she sold half her books she had 20. To find how many she started with you do the opposite of dividing by 2, multiplying by 2. So:
20 x 2 = 40.
She started with 40 books.
