To solve this problem, we need to find the element \( b_{23} \) in matrix \( B \). Since matrix \( A \) is given as equal to matrix \( B \), the corresponding elements in both matrices are identical. Therefore, \( b_{23} \) will be the same as the element in the 2nd row and 3rd column of matrix \( A \).

### Matrix \( A \):
\[
A = \begin{bmatrix} 2 & 0 & -9 & 11 \\ 18 & -7 & 0 & 21 \end{bmatrix}
\]

From this matrix:
- The element in the 2nd row and 3rd column is **0**.

### Answer
The value of \( b_{23} \) is **0**.
