It sounds like you might be trying to reduce a matrix to a certain form, possibly aiming to achieve a zero in the fourth row in the context of solving a system of equations, matrix manipulation, or row reduction. 

To transform 23 to 0 in the fourth row, here are some general steps depending on your matrix's layout and the position of 23:

1. **Identify Row Operation:** Determine if you can add or subtract a multiple of another row to the fourth row to achieve the zero. For example, if you have a 23 in the position you want to zero out, identify another row that has an element in that column you can use to cancel it.

2. **Row Addition/Subtraction:** If there’s a suitable row, multiply it by a factor that allows the addition or subtraction to turn 23 to zero. For instance, if another row has a -1 in that column, multiplying that row by 23 and adding it to the fourth row would zero out the 23.

3. **Scaling (if necessary):** If a direct row operation isn’t possible, consider scaling the entire fourth row so you can perform row operations more easily.

4. **Verification:** After performing the row operation, double-check to ensure that only the 23 has turned to zero without altering other needed values.

If you provide more specifics about the matrix, I can guide you through the exact operation.
