Question

3-x/3+x=-47/3³+26 ответ 50 дайте решение

Answer 1

3 - x/3+x = 702/27
3-x = 702/27 * (3 +x)
3 -x = 702(3 + x) /27
27 (3-x) = 702(3+x)
81 - 27x = 2106 +702x
2025 = -729x
x = -2 + 567/729

Answer 2

3 - х/3 +х = -47/3³ +26 3 - х/3 +х = -47/9 +26 3-26 -х/3 +х = -47/9 -23 -х/3 +х =47/9 9*(-23 - х/3 +х) = 47 -207 -3х +9х =47 6х = 207+47 6х = 254 х = 254/6 х = 42
