Question

Ecuación 4x+1/3 = 12x-3/7

Answer 1

Despejando la variable " x " :

4x + 1/3 = 12x - 3/7
( 12x + 1 ) / 3 = ( 84x - 3 ) / 7
7 ( 12x + 1 ) = 3 ( 84x - 3 )
84x + 7 = 252x - 9
252x - 84 = 7 + 9
168x = 16
x = 16/168
x = 2/21                       → Solución

Answer 2

 4x+1/3 = 12x-3/7

4x= 12x-3/7-1/3

4x= 12x-16/21

4x-12x= -16/21

-8x= -16/21

x= -16/21 Sobre -8

x= 2/21
