Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did gia have to begin

Let me assume Gia had total books in starting = x books.

Number of books she got today = 5 books.

Number of books she returned = 3.

Total remaining books = 6 books.

We can setup an equation as

Total books in starting + Number of books she got today - Number of books she returned = Total remaining books.

Therefore,

x + 5 - 3 = 6.

x + 2 = 6.

Subtracting 2 from both sides, we get

x+2-2=6-2.

x=4.

Therefore, Gia had total 4 books in starting.

I'm pretty sure she had four books.
