b) 2x = -7


c) 3x + 2 = 2x - 11

d) 2x = 16

e) x = -5
2

f) 2x + 14 = 5x - 1

g) 4x - 5 = 6x + 11

Answer 1

Resposta:

a) x - 17 = -9

x = -9 + 17

x = 8

B) 2x = -7

x = -7/2

x = - 3,5

C)3x +2 = 2x - 11

3x -2x = -11 -2

X= -13

D)2x = 16

x = 16/2

x = 8

E)n entendi

F)2x +14 = 5x -1

2x -5x = -1 -14

-3x = -15 . (-1)

3x = 15

x = 15/3

x= 5

G)4x -5 = 6x + 11

4x - 6x = 11 + 5

-2x = 16 . (-1)

2x = 16

x = 16/2

x = 8
