Question

1/6-x/2=-2x/3+1/4
$\frac{ 1}{6} - \frac{x}{2} = - \frac{2x}{3} + \frac{1}{4}$
me ajuda pfv​

Answer 1

Resposta:

x = - 1 / 14

Explicação passo-a-passo:

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

( 1 / 6 ) - ( 3x / 6 ) = ( 8x / 12 ) + ( 3 / 12 )

( 1 - 3x ) / 6 = ( 8x + 3 ) / 12

12 ( 1 - 3x ) = 6 ( 8x + 3 )

6 ( 8x + 3 ) = 12 ( 1 - 3x )

8x + 3 = 12 ( 1 - 3x ) / 6

8x + 3 = 2 ( 1 - 3x )

8x + 3 = 2 - 6x

8x + 6x = 2 - 3

14x = - 1

x = - 1 / 14
