To solve for c in the equation 89 = 8c + 25, we need to isolate c on one side of the equation. Here are the steps:
1. Subtract 25 from both sides of the equation to get the term with c on its own.
89 - 25 = 8c + 25 - 25
2. This simplifies to:
64 = 8c
3. To solve for c, divide both sides by 8:
64 / 8 = 8c / 8
4. This simplifies to:
8 = c
Therefore, c equals 8.
