Пошаговое объяснение:
1/6x+6,5=0,6(2 7/9x+3 1/3)
(1/6)х + 6,5 = 0,6(25х/9 + 10/3)
х/6 + 6,5=5х/3 + 2
х/6 - 5х/3 = 2 - 6,5
х/6 - 10х/6 = - 4,5
-3х/2 = -4,5
-1,5х = -4,5; х=3

1/6х + 6,5 = 0,6(2. 7/9х + 3. 1/3)
1/6х + 65/10 = 6/10(25/9х + 10/3)
1/6х + 65/10 = 150/90х + 60/30
1/6х + 13/2 = 5/3х + 2
1/6х - 5/3х = 2 - 13/2
1/6х - 10/6х = 1. 2/2 - 6. 1/2
-9/6х = 1. 2/2 - 5. 3/2
-3/2х = -4. 1/2
-3/2х = -9/2
х = -9/2 : (-3/2)
х = -9/2 * (-2/3)
х = 18/6
х = 3
