Question

Математика: Решите линейные уравнения 2х+3=0; -4х+3=-2; 6+5х=2х+9; -4(3-х)=2х+7; 7+3(2х+1)=4

anastasyaantonova07 · Answer

2х + 3 = 02х = 3х = 3/2х = 1,5-4х + 3 = -2-4х = -2 - 3-4х = -54х = 5х = 5/4х = 1 1/46 + 5х = 2х + 95х - 2х = 9 - 63х = 3х = 1-4(3 - х) = 2х + 7-12 + 4х = 2х + 74х - 2х = 7 + 122х = 19х = 19/2х = 9 1/27 + 3(2х + 1) = 47 + 6х + 3 = 410 + 6х = 46х = -6х = -1...
