8х+3(7-2х)=4х+3 23-4(3х+8)=1-17х

Question

8х+3(7-2х)=4х+3

23-4(3х+8)=1-17х

Answer 1

8х+21-6х=4х+3

8х-6х-4х=3-21

2х=18

х=9

ответ: х=9

23-12х-32=1-17х

-12х+17х=1-23+32

5х=10

х=2

ответ: х=2

Answer 2

1)8х+3(7-2х)=4х+3

8х+21-6х=4х+3

8х-6х-4х=3-21

-2х=-18

х=-18/-2=9

2)23-4(3х+8)=1-17х

23-12х-32=1-17х

17х-12х=32-23+1

5х=10

х=10/5=2
