To find the number of baskets \( b \) that Andrew made, we can set up the equation based on the information provided.
Joe made 9 baskets, which is 2 more than Andrew. Therefore, we can express this relationship with the equation:
\[ b + 2 = 9 \]
To solve for \( b \), we can subtract 2 from both sides:
\[ b = 9 - 2 \] \[ b = 7 \]
So, Andrew made 7 baskets. The completed equation is:
\[ b + 2 = 9 \]
