Answer 2

Ответ:

1)-(4х-2)-(5х+2)=7х-15

1)-(4х-2)-(5х+2)=7х-15-4х+2-5х-2=7х-15

1)-(4х-2)-(5х+2)=7х-15-4х+2-5х-2=7х-15-9х=7х-15

1)-(4х-2)-(5х+2)=7х-15-4х+2-5х-2=7х-15-9х=7х-15-9х-7х=-15

1)-(4х-2)-(5х+2)=7х-15-4х+2-5х-2=7х-15-9х=7х-15-9х-7х=-15х=15/16

2)(14х-12)-(7х-10)-(7х+11)=2х-3

14х-12-7х+10-7х-11=2х-3

0-13=2х-3

-13=2х-3

-12х=-3+13

-12х=10

х=-5
