Answer 1

a)

4x + 8 = 20

4x = 20 - 8

4x = 12

x = 12 / 4

x = 3

b)

12x - 13 = 26

12x = 26 + 13

12x = 39

x = 39 / 12

x = 3.25

c)

9x - 8 = -72

9x = -72 + 8

9x = -64

x = -64 ÷ 9

x = -7.11

d)

17x - 13 = -50

17x = -50 + 13

17x = -37

x = -37 ÷ 17

x = -2.17

e) -9x + 40 = 79

79 + 40 = 9x

119 = 9x

119 / 9 = x

13.22 = x

Answer 2

Holaa :D

a) 4x+8=-20

4x=-20-8

4x=-28

x=-28/4

x=-7

B) 12x-13=26

12x=26+13

12x=39

x=39/12

x=13/4

C)9x-8= - 72

9x=-72+8

9x=-64

x=-64/9

D)17x-13=-50

17x=-50+13

17x=-37

x=-37/17

E)-9x+40=79

-9x=79-40

-9x=39

-x=39/9

-x=13/3

x=-13/3

Espero que te sirva <3
