Answer 1

6)10 + 0,2х = 90+х

0.2x-x=90-10

-0.8=80

x=80/-0.8

x=-100

Ответ: -100

11. 4(1 - 0,5x)= 2(3 + 2)

4-2x=6+4

-2x=10-4

-2x=6

x=6/-2

x= -3

Ответ: -3

1) 24-х= 12+x

-х-х=12-24

-2х= -12

х= -12/-2

х=6

Ответ:6

12) -3(2- 15x) =- 6

-6+45х= -6

45x= -6+6

45x=0

x=0

Ответ:0

7) 4х – 0,6 = 0,6+х

4x-x=0.6+0.6

3x=1.2

x=1.2/3

x=0.4

Ответ:0.4

2) 9x + 1 = 2х- 6

9x-2x= -6-1

7x= -7

x= -7/7

x= -1

Ответ: -1

13. 4(3-х)- 11 =7 (2х-5)

12-4x-11=14x-35

-4x-14x= -35-12+11

-18x= -36

x= -36/-18

x=2

Ответ:2

3) 6х – 150 = 85 +х

6x-x=85+150

5x=235

x=235/5

x=47

Ответ:47

8)x– 8 = 2,4х- 15

x-2.4x= -15+8

-1.4x= -7

x= -7/-1.4

x=5

Ответ:5

Answer 2

It seems like you've provided a list of equations. Would you like me to help you solve these equations for the variable x? If so, I'd be happy to assist. Just let me know which equation you'd like me to start with, or if you'd like me to solve all of them.
