She started with 7. You're not given a starting value, but before she began cutting the pieces of paper, she grabbed 7 more. She ended with 28 half sheets. Basically, 7 × 2 = 14. Then, you multiply 14 by 2, which will get you 28 sheets. So she started with 7 sheets.
I hope this helps because I might sound complicated^^

3x = 5/6
6 1 6
_ x _ = __
5 3 15
6/15=2/5
Cross multiply
(3x - 1)(4x + 5) = (2x + 6)(6x - 4)
12x^2 + 11x - 5 = 12x^2 + 28x -24
Solve for x
-17x = -19
x = 19/17
