Question

Dada a equaçao x/3-1=x/6+x/4,o valor de x e:

​

Answer 1

Resposta: x= -12

Explicação passo-a-passo:

$\frac{x}{3} -1 = \frac{x}{6} + \frac{x}{4} \\. (mmc 1,3,4,6 = 12 )\\\\\\\frac{4x}{12} -\frac{12}{12} = \frac{2x}{12} +\frac{3x}{12}$

4x/12 - 5x/12 = 12/12

-x/12=12/12

-x = 12

x= -12
