Решите плиз

Answer 1

1)х=12
2)х=2
3)х=-5
4)х=-4/-5
5)х=6
6)х=10
7)х=3
8)х=-7.5

Answer 2

8. 4(3-2х)+24=2(3-2х)

12-8х+24=6-4х

-8х+4х=-12-24+6

-4х=-30

х=7,5

7. 28-4х=19-х

-4х+х=-28+19

-3х=-9

х=3

6. 4х-13=6х+7

4х-6х=13+7

-2х=20

х= -10

5. 7х+27=6х+21

7х-6х=-27+21

х=-6

4. 36+20х=50х+12

20х-50х=-36+12

-30х=-24

х=0,8

3. 3х-17=8х+18

3х-8х=17+18

-5х=35

х=-7

2. 23-4(3х+8)=1-17х

23-12х-32=1-17х

-12х+17х=-23+32+1

5х=10

х=2

1. 8х+3(7-2х)=4х+3

8х+21-6х=4х+3

8х-6х-4х=-21+3

-2х=-18

х=9
