To find the equation that can be used to determine the number of baskets, \( b \), that Andrew made, we know that Joe made 9 baskets, which is 2 more than what Andrew made.
This can be expressed as:
\[ b + 2 = 9 \]
We can rearrange this to find \( b \):
- Subtract 2 from both sides:
\[ b = 9 - 2 \]
Thus, the equation would look like this:
\[ b + 2 = 9 \]
So, to complete your request for the equation format:
\( b + 2 = 9 \)
Additionally, we can fill in the blanks in your original format:
- \( b + b + 2 = 9 \)
In this case, you need to recognize there is one \( b \) from Andrew's baskets and one \( b \) from Joe and Andrew comparison, but only one \( b \) is needed for Andrew's made baskets.
So the simplest and most relevant equation is:
\[ b + 2 = 9 \]
Where \( b \) is the number of baskets made by Andrew.
