Question

resolva as equações de 1 grau 2(×-1)/3+3(1+×)/2=1/2-×-1/3​

Answer 1

Resposta:

x = - 4/19

Explicação passo-a-passo:

2(×-1)/3 + 3(1+×)/2= 1/2 - × - 1/3​

Mmc (2,3)= 6

[2.2(x-1) +3.3(1+x)]/6 = [3.1 - 6x - 2.1]/6

4(x-1) + 9(1+x) = 3 - 6x - 2

4x - 4 + 9 + 9x = 1 - 6x

13x + 5 = 1 - 6x

13x + 6x = 1 - 5

19x = - 4

x = - 4/19
