Найти корень уравнения -2х+1-3(х-4)=-4(3-х)+4

-2х + 1 - 3 ( х - 4 ) = -4 ( 3 - х ) + 4
-2х + 1 - 3х + 12 = -12 + 4х + 4
-2х - 3х - 4х = -12 + 4 - 1 - 12
-9х = -21
х = 21/9 = 2 1/3.
Ответ : х = 2 ⅓.

Удачи)))

–2х+1–3(х–4)=–4(3–х)
–2х+1–3х+12=–12+4х
–2х–3х–4х=–1–12–12
–9х=–25
х=–25:(–9)
x=25/9
x=18
