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.
