Me ajudem aqui:
Resolva a equação: 1/2 - x = 6 (1/3 - x )
1/2 - x = 6·1/3 - 6x
1/2 - x = 2 -6x
1 - 2x = 4 - 12x
10x = 3
x = 3/10
1-6x=12(1/3--x)
1-6x=4-4x
-6x+4x=4-1
-2x=3
2x=-3
x=-3/2

1/2 - x = 6·1/3 - 6x
1/2 - x = 2 -6x
1 - 2x = 4 - 12x
10x = 3
x = 3/10
1-6x=12(1/3--x)
1-6x=4-4x
-6x+4x=4-1
-2x=3
2x=-3
x=-3/2
