Solve the equation: 4 - 7.5(x + 9) = -74.3

Ответ:

Let's solve the equation step by step: 1. **Original equation:** $$4 - 7.5(x + 9) = -74.3$$ 2. **Distribute -7.5:** $$4 - 7.5x - 67.5 = -74.3$$ 3. **Combine constants on the left side:** $$-7.5x - 63.5 = -74.3$$ 4. **Add 63.5 to both sides:** $$-7.5x = -74.3 + 63.5$$ $$-7.5x = -10.8$$ 5. **Divide both sides by -7.5:** $$x = \frac{-10.8}{-7.5}$$ $$x = 1.44$$ Therefore, the solution to the equation is (x = 1.44). **Final Answer:** The final answer is $$\boxed{1.44}$$
