Answer 1

Answer:

4

Step-by-step explanation:

Given: Gia got some books from the library yesterday. She got 5 books today after returning 3. Gia now has 6 books.

To Find: How many library books did gia begin with.

Solution:

Let the number of library books gia begin with $=\text{x}$

Number of books gia got today $=5$

Number of books gia returned  $=3$

Total number of books Gia has $=(\text{Total number of books is started with})+(\text{number of books gia got})-(\text{books gia returned})$

                                        $\text{x}+5-3$

                                         $\text{x}+2$

Total number of books gia has $=6$

now,

                 $\text{x}+2=6$

                 $\text{x}=6-2$

                 $\text{x}=4$

Hence number of books gia started with is 4

Answer 2

The number of books Gia started with is 4

Let the number of books she got yesterday = x

Total Number of books she has gotten = 6

Books she got today = 3

Number of books she returned = 5

Expressing this as an equation :

Total books gotten = (x + 5 - 3)

6 = x + 5 - 3

6 = x + 2

6 - 2 = x

x = 4

The number of books Gia started with is 4.
