Question

4х+5(3-2х)=5-11х

Answer 1

4х+5(3-2х)=5-11х

4х+15-10х=5-11х

15-6х=5-11х

15-5=-11х+6х

10=-5х

х=-2

Answer 2

4х+5(3-2х)=5-11х

5(3-2х)=5-11х-4х

5(3-2х)=5-15х

5(3-2х)=5(1-3х)

3-2х=1-3х

-2х+3х=1-3

х=-2                                  

4*(-2)+5(3-2*(-2))=5-11*(-2)

                -8+5*7=5+22

                      27=27

Ответ: -2.
