a - 2 x - 8 = 3 x - 11

b - 8 x + 20 = 4 x

c- x / 2 + 5 = 3 x / 4 + 3

d- 2 / 3 - 2 = x/ 9 + 3

Answer 1

Resposta:

Explicação passo-a-passo:

a-

2x-8=3x-11

2x-3x = -11 +8

-x = -3

x = 3

b-

-8x +20= 4x

20 = 4x +8x

20 = 12 x

x = 20/12

x = 5/3

c-

x/ 2+ 5 =3x/4 +3

x/2 - 3x /4 = 3 - 5

2x - 3x  = 12 - 20

- x = -8

x = 8

d-

2/3 - 2 = x/9 +3

6 - 18 = x + 27

6- 18 - 27 = x

x = -39
