Respuesta:

este si esta bien

Explicación paso a paso:

-[-(3-2x)-4(2-x)]-1=-2[-3(1-3x)-3(1-x)+2]

-[-3+2x-4(2-x)]-1=-2[-3(1-3x)-3(1-x)+2]

-[-3+2x-8+4x]-1=-2[-3(1-3x)-3(1-x)+2]

-[-3+2x-8+4x]-1=-2[-3+9x-3(1-x)+2]

-[-3+2x-8+4x]-1=-2[-3+9x-3+3x+2]

-[-11+2x+4x]-1=-2[-3+9x-3+3x+2]

-[-11+6x]-1=-2[-3+9x-3+3x+2]

-[-11+6x]-1=-2[-4+9x+3x]

-[-11+6x]-1=-2[-4+12x)

11+6x-1=-2[-4+12x)

11+6x-1=8-24x

10-6x=8-24x

10-6x+24x=8

-6x+24x=8-10

18x=8-10

18x=-2

x= -1/9
