Скласти рівняння) даю….. хм 80 балов

Answer 1

2/3 * (1/3x - 1/2) = 4x + 2 1/2
2/9 x - 1/3 = 4x + 2,5 | * 9
2x - 3 = 36x + 22,5
-25,5 = 34x
x = - 25,5/34
x = - 3/4
x = - 0,75

Answer 2

Ответ:

-3/4

Пошаговое объяснение:

2/3(1/3х - 1/2) = 6х - 2(х - 1. 1/4)

2/3(1/3х - 1/2) = 6х - 2(х - 5/4)

2/9х - 2/6 = 6х - 2х + 10/4

2/9х - 1/3 = 4х + 5/2

2/9х - 4х = 5/2 + 1/3

2/9х - 3. 9/9х = 15/6 + 2/6

-3. 7/9х = 17/6

-34/9х = 17/6

х = 17/6 : (-34/9)

х = 17/6 * (-9/34)

х = 1/2 * (-3/2)

х = -3/4
