Question

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

Answer 1

1-(1-x)+2(x+3)=4-(6-x)
1 - 1 + x + 2x + 6 = 4 - 6 + x
3x + 6 = - 2 + x
3x - x = - 2 - 6
2x = - 8
x = - 8/2
x = - 4

Solución.
x = - 4

Answer 2

RESOLUCION :
1-(1-x)+2(x+3)=4-(6-x)
1-1+x +2x+6= 4-6+x
x+2x-x=4-6-1+1-6
2x = -8
$\frac{2x}{2} = \frac{-8}{2}$
x = -4
