Даю 40 поинтов. Но нужно решить уравнение с проверкой 6(4x - 7) - 3 (5 - 8x) = 0. ​

:

6(4х - 7) - 3(5 - 8х) = 0

24х - 42 - 15 + 24х = 0

24х + 24х = 0 + 42 + 15

48х = 57

х = 57 : 48

х = 57/48

х = 1. 9/48

х = 1. 3/16

Проверка:

6(4 * 1. 3/16 - 7) - 3(5 - 8 * 1. 3/16) = 0

6(4 * 19/16 - 7) - 3(5 - 8 * 19/16) = 0

6(1 * 19/4 - 7) - 3(5 - 1 * 19/2) = 0

6(19/4 - 7) - 3(5 - 19/2) = 0

114/4 - 42 - 15 + 57/2 = 0

28. 2/4 - 57 + 28. 1/2 = 0

28. 1/2 - 57 + 28. 1/2 = 0

56. 2/2 - 57 = 0

57 - 57 = 0

0 = 0
