Question

(7-5х)-(8-4х)+(5х+6)=8 (3-2х)+(4-3х)+(5-5х)=12+7х

Answer 1

(7-5х)-(8-4х)+(5х+6)=8
7-5х-8+4х+5х+6=8
4х=3
х=3/4
Ответ:3/4
 (3-2х)+(4-3х)+(5-5х)=12+7х
3-2х+4-3х+5-5х=12+7х
17х=0

х=0
Ответ: 0

Answer 2

(7-5х)-(8-4х)+(5х+6)=8

7-5х-8+4х+5х+6=8

4х=3

x=3/4

 

(3-2x)+(4-3x)+(5-5x)=12+7x

3-2x+4-3x+5-5x=12+7x

17x=0

x=0
