Question

(2x-14)-(6x-3)=1
Решить уравнение

Answer 1

(2x-14)-(6x-3)=1

2x-14-6x+3=1

2x-6x=1-3+14

-4х=12

4х=-12

х=-12/4

х=-3

Ответ: х=-3

Answer 2

(2x - 14) - (6x - 3) = 1,

2х - 14 - 6х + 3 = 1,

2х - 6х = 1 + 14 - 3,

-4х = 12,

х = -3,

проверка:

(-3*2 + 14) - (-3*6 - 3) = 1,

(-6 - 14) - (-18 - 3) = 1,

-20 - (-21) = 1,

-20 + 21 = 1,

1 = 1
