🔍 Explanation:

To solve linear equations like $ ax + b = c $, we follow these steps:
1. Isolate the variable term (e.g., move constants to the other side).
2. Divide both sides by the coefficient of $ x $ to find $ x $.
This method works for all forms as long as you perform the same operation on both sides.
