Question

4(2-3х)-2(9х-8)=15(1-х)+3(4-х)
7(3-х)-3(х-4)=5(3+2х)-2(-3-2х)
4(х-16)-(8-х)=10(х+1)-2(15+8х)

Answer 1

1. 4(2-3х)-2(9х-8)=15(1-х)+(4-х)
8-12х-18х+16-15+15х-12+3х=0
18х-3=0
18х=3
х=6

Answer 2

плиз помогите

Answer 3

2. 7(3-х)-3(х-4)=5(3+2х)-2(-3-2х)
21-7х-2х+12-15-10х-6-4х=0
-24х+12=0
х=2
