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

Answer 1

x-1 - 3(x-3)=-6
x-1-3x+9=-6
-2x+8=-6
-2x=-6-8
-2x=-14
x=14/2
x=7

Answer 2

Resolver.

(x - 1)/6 - ( x - 3)/2  = - 1
(x - 1)/6 - 3(x - 3)/ 6 = (-1)(6)/6    simplificamos el 6
(x - 1) - 3( x - 3) = - 6
x - 1 - 3x + 9 = -6
-2x + 8= - 6
8 +6 = 2x
14 = 2x
14/2 = x
x = 7

Respuesta.
x = 7
