2.​

Answer 1

Resposta:

a) x = -9-17

x = -26

b) 3x-2x = -11-2

x = -13

C) x = 15/3

x = 5

d) x = -12/4

x = -3

e) x = -5

f) x = -7/2

g) x = 16/2

x = 8

h) 2x + 6 = 14

2x = 14-6

2x = 8

x = 8/2

x = 4

i)7x - 14 = -21

7x = -21+14

7x = -7

x = -7/7

x = -1

J) 2x-5x = -1+14

-3x = 13

x = -(13/3)
