To determine the number of hours \( h \) that Moira needs to read to finish the book, we can set up the equation based on the total hours required and the hours she has already read.
We know:
- Total hours needed: 214
- Hours already read: 178
The equation can be structured as:
\[ h + 178 = 214 \]
Thus, the completed equation is:
h + 178 = 214
