Resposta:

b 11 espero te ajudar linda

Answer 2

Resposta:

a) x = 4

b) x = 6

c) x = 1

d) x = 3

e) x = 6

Explicação passo-a-passo:

a) 6x = 2x + 16

6x - 2x = 16

4x = 16

x = 16 : 4

x = 4

b) 2x - 5 = x + 1

2x - x = 1 + 6

x = 6

c) 2x + 3 = x + 4

2x - x = 4 - 3

x = 1

d) 5x + 7 = 4x + 10

5x - 4x = 10 - 7

x = 3

e) 4x - 10 = 2x + 2

4x - 2x = 2 + 10

2x = 12

x = 12 : 2

x = 6
