Question

$\frac{x}{2} + \frac{x}{6} = 10$
​

Answer 1

Resposta:

Explicação passo-a-passo:

X/2 + X/6 = 10/1

MMC  2 e  6  = 2  * 6 = 12

12 : 2 = 6  * x = 6x >>>

12 : 6 = 2 * x  = 2x >>>>

12 :  1  = 12  *10  = 120 >>>

elimina mmc

reescrevendo

6x + 2x = 120

(+6 + 2 )x  = 120

8x = 120

x = 120/8  =15>>>>> resposta
