Spencer and Sydney both have many books at home. Together they have 65 books. Spencer has 9 fewer books than Sydney.

Ahh --

x + x + 9 = 65

2x = 56

x = 28

Spencer has 28 books

Spencer and Sydney both have many books at home. Together they have 65 books. Spencer has 9 fewer books than Sydney. How many books does Spencer have?

What is your question?

To find out how many books Spencer has, let's assign a variable to represent the number of books Sydney has.

Let's call the number of books Sydney has "S".

According to the problem, Spencer has 9 fewer books than Sydney. So, we can express the number of books Spencer has as "S - 9".

Now, we know that together they have 65 books.

So, we can set up the equation:

(S + (S - 9)) = 65

Now, let's solve this equation to find the value of S.

Combining like terms:
2S - 9 = 65

Adding 9 to both sides of the equation:
2S = 74

Dividing both sides of the equation by 2:
S = 37

Therefore, Sydney has 37 books.

To find out how many books Spencer has, we can substitute the value of S into the expression we created earlier:

Spencer's number of books = S - 9 = 37 - 9 = 28

Hence, Spencer has 28 books.
