Question

реши уравнение x-1 2/7=4x+2 5/14

Answer 1

х - 1 2/7 = 4х + 2 5/14
х - 4х = 2 5/14 + 1 2/7
- 3х = 2 5/14 + 1 4/14
- 3х = 3 9/14
- 3х = 51/14
х = 51/14 : (-3)
х = 51/14 * (-1/3)
х = - 17/14
х = - 1 3/14
-----------------------------------
Проверка:
- 1 3/14 - 1 4/14 = 4 * (-1 3/14) + 2 5/14
- 2 7/14 = - 4 12/14 + 2 5/14
- 2 7/14 = - 2 7/14

Answer 2

x-9/7=4x+33/14
x-4x=33/14+9/7
-3x=51/14
x=-17/14
