Question

R/6-r-3/4=2r-1/3 me ajude

Answer 1

Resposta:

r = - 5/34

Explicação passo a passo:

r/6 - r - 3/4 = 2r - 1/3

r/6 - r = 2r - 1/3 + 3/4

r/6 - r = 2r - 4/12 + 9/12

r/6 - r = 2r + 9/12 - 4/12

r/6 - r = 2r + (9 - 4)/12

r/6 - r = 2r + 5/12

r/6.6 - 6r = 6.2r + (5/12).6

r - 6r = 12r + 30/12

r - 6r = 12r + 5/2

-5r = 12r + 5/2

-5r - 5/2 = 12r

- 5/2 = 12r + 5r

- 5/2 = 17r

17r = - 5/2

r = - 5/2/17

r = - 5/2.17

r = - 5/34
