What is the sum of a number added, subtracted, and divided equal to 8.6?

Let this number be X
x+x + x-x + x/x =8.6
2x + 0 + 1 =8.6
2x + 1 =8.6
2x =8.6-1
2x =7.6
x =7.6/2
x =3.8

12. Did Maxwell calculate the speed of light? I don't believe that one can calculate the speed of light by pure theory. Relativity only says that the speed of light is constant
13. Do I reach the speed of light like this? Everyone knows that no one can reach the speed of light, but if I move to the left at half the speed of light and you move to the right at the same speed, then I'm not sure if you have reached the speed of light
14. Who, when and how does the speed of light work out? Who knows?
15. Is that faster than light? If a person goes against the light and the speed is V, then the speed of the photon relative to the person is C + V. although V is very small relative to the speed of light, it surpasses after all

17. Will the measured speed of light be faster than the actual speed? The first thing to say is that my idea is definitely wrong, but I really don't know what is wrong, so I want to discuss it with you. Anyone who is interested can say two sentences If the distance between the earth and the sun is s, and we know that the time required for light to pass from the sun to the earth is t, then we can calculate the speed of light as S / T = C, but due to the tardiness effect, the distance between the earth and the sun will be reduced to s', so the calculated speed of light is v = s' / T, because s'
