Проверьте корректность решения уравнения: 5x - 10 = 15, x = 5

• The solution is incorrect. When x = 5, the equation becomes 5(5) - 10 = 15, which simplifies to 25 - 10 = 5, and 5 = 15. Therefore, the correct solution is x = 5.

• The solution is incorrect. When x = 5, the equation becomes 5(5) - 10 = 15, which simplifies to 25 - 10 = 15, and 15 = 15. Therefore, the correct solution is x = 5.

• The solution is incorrect. When x = 5, the equation becomes 5(5) - 10 = 15, which simplifies to 25 - 10 = 15, and 15 = 15. Therefore, the correct solution is x = 5.

• The solution is correct. x = 5 is the correct answer.
