answer:
To solve the equation 25 - 3x = 40, we can follow these steps:
1. Start with the equation: 25 - 3x = 40.
2. Simplify the equation by subtracting 25 from both sides to isolate the variable:
25 - 3x - 25 = 40 - 25.
Simplifying further gives: -3x = 15.
3. Divide both sides of the equation by -3 to solve for x:
-3x / -3 = 15 / -3.
This simplifies to: x = -5.
Therefore, the solution to the equation 25 - 3x = 40 is x = -5.
