We know that Joe made 9 baskets and that this is 2 more than the number of baskets Andrew made. We can express the relationship with an equation.
Let \( b \) be the number of baskets that Andrew made. According to the information given, we can set up the equation as follows:
\[ b + 2 = 9 \]
So we can complete the equation:
b + 2 = 9
