Решите уравнения ! умоляю...

ИльяВайсблат2 -3(-х - 5) - 5(х + 4) = -4(х - 6) -(- х + 3)
3х + 15 - 5х - 20 = -4х + 24 +х - 3
3х - 5х + 4х - х = 24 - 3 - 15 + 20
х = 26
6(- х + 2) - (х - 5) = 2(х - 3) + 3(- х - 4)
-12х + 12 - х + 20 = 2х - 6 - 3х - 12
- 12х - х - 2х + 3х = - 6 - 12 - 12 - 20
-12х = - 50
х = - 50 / -12
х = 50/12 = 4 2/12 = 4 1/6
2х - (- 4х) + 12 - (- 3) = - (- 5) + х
2х + 4х + 12 + 3 = 5 + х
2х + 4х - х = 5 - 12 - 3
5х = - 10
х = - 10 / 5
х = - 2

Verified answer

-3(-х-5)-5(х+4)=-4(х-6)-(-х+3)
3х+15-5х-20=-4х+24+х-3
-2х-5=-3х+21
-2х+3х=21+5
х=26
