Question

a) x - 17 = -9
d) 2x = 16
b) 2x = -14
e) x + 14 = 5x - 1
c) 3x + 2 - 2x - 11
f) 4x - 5 = 6x + 11​

Answer 1

RESPOSTA:

a) x = 8

d) x = 8

b) x = -7

e) x = 3,75

c) x = -13

f) x = -8

RESOLUÇÃO:

a)

x - 17 = -9

x = -9 + 17

x = 8

d) 2x = 16

x = 16/2

x = 8

b) 2x = -14

x = -14/2

x = -7

e) x + 14 = 5x - 1

x + 15 = 5x

15 = 4x

15/4 = x

3,75 = x

x = 3,75

c) 3x + 2 = 2x - 11

x + 2 = -11

x = -13

f) 4x - 5 = 6x + 11

4x - 16 = 6x

-16 = 2x

-16/2 = x

-8 = x

x = -8

Espero ajudar.
