Question

решите уравнение памагите
3(-2x+1)-2(x+13)=7x-4(1-x)

Answer 1

Ответ:

-6х+3-2х-26=7х-4+4х

-6х-7х-2х-4х=26-3-4

-19х=19

-х=1

х=-1

Answer 2

3(-2x+1)-2(x+13)=7x-4(1-x) 3−2x−1−2(x+13)=7x−4(1−x) 2−2x−2(x+13)=7x−4(1−x) 2−2x−2x−26=7x−4(1−x)

2−4x−26=7x−4(1−x) −24−4x=7x−4(1−x)

-24-4x=11x-4

-24-4x-11x=-4

-24-15x=-4 -15x=-4+24 -15x=20
