Answer 1

Respuesta:

−7x − 11 = −9x – 27

-7 x + 9x = -27 + 11

2 x = -16

x= -16/2

x= -8

−3x − 4 = −2x + 5

-3 x + 2 x = 5 + 4

-1 x = 9

x= 9/-1

x= -9

11x − 10 = −11x – 208

11x + 11 x = -208 + 10

22 x = -198

x = -198/22

x= -9

−8x − 6 = −10x − 22

-8 x + 10 x = -22 + 6

2 x = -16

x = -16/2

x= -8

5x + 6 = 8x − 18

5 x - 8 x = -18 - 6

- 3 x = -24

x= -24/-3

x = 8

−4x + 2 = −7x + 14

- 4 x + 7 x = 14 - 2

3 x = 12

x = 12/3

x = 4

−6x + 2 = −5x + 4

- 6 x + 5 x = 4 - 2

- 1 x = 2

x = 2/-1

x = -2

−6x + 7 = 10x − 169

- 6 x - 10 x = - 169 - 7

- 16 x = - 176

x = -176/ -16

x = 11

7x − 7 = 10x − 37

7 x - 10 x = -37 + 7

-3 x =  -30

x = -30/-3

x = 10

−9x − 8 = −4x + 37

- 9 x + 4 x = 37 + 8

- 5 x = 45

x = 45/ -5

x = -9

−3x + 9 = 2x − 26

-3 x - 2 x = -26 - 9

- 5 x = - 35

x = -35/-5

x = 7

5x + 7 = 10x + 32

5 x - 10 x = 32 - 7

- 5 x = 25

x = 25/-5

x = -5

−7x − 5 = 10x + 80

- 7 x - 10 x = 80 + 5

-17 x = 85

x = 85/ -17

x = -5

−11x − 3 = 4x + 117

- 11 x - 4 x = 117 + 3

- 15 x = 120

x = 120/ - 15

x = -8

Hola, espero sean de ayuda!
