Question

a)12x + 14 = 5x-1
b)13 (x + 2)+5=x+12
g)4 x -5 = 6 x +11​

Answer 1

Explicação passo-a-passo:

12×-5×=-1-14

7×=-15

×=-15/7

13×+26+5=×+12

13-×=12-5-26

12×=12-31

12×=-19

×=-19/12

4×-6×=11+5

-2×=16(-1)

2×=-16

×=-16/2

×=-8

Answer 2

Resposta:

Explicação passo-a-passo:

a) 12x + 14 = 5x - 1

12x - 5x = - 1 - 14

7x = - 15

x = - 15/7

b) 13 (x + 2)+5=x+12

13x + 26 + 5 = x + 12

13x - x = 12 - 26 -5

12x = - 19

x = - 19/12

c) 4 x -5 = 6 x +11

4x - 6x = 11 + 5

- 2x = 16

x = - 16/2

x = - 8
