Question

2(x-1)/3+3(1+x)2=1/2-x-1/3

Answer 1

Resposta: x = - 13/19

Explicação passo-a-passo:

2(x-1)/3+3(1+x)2=1/2-x-1/3

2x - 2/3 + 3 + 3x/2 = 1/2 - x - 1/3 mmc 3,2 = 6

(4x - 4/6 )+ (18 + 9x/6) = 3/6 -6x/6 -2/6 ( exclui os denominadores

4x - 4 + 18 + 9x = 3 - 6x - 2

4x + 9x + 6x = 3 - 2 + 4 - 18

19x = -13

  x = - 13/19
