Question

-5(x + 4) = 2x – 2[2x - (2x + 1)] + 4x ecuaciones nivel 3​

Answer 1

----------------------------------------------------------

-5(x+4)=2x-2[2x-(2x+1)]+4x

-5x-20=2x-2[2x-(2x+1)]+4x

-5x-20=2x-2[2x-2x-1]+4x

-5x-20=2x-2[-1]+4x

-5x-20=2x+2+4x

-5x-20=6x+2

-5x-20+20=6x+2+20

-5x=6x+22

-5x-6x=6x+22-6x

-11x=22

-11x/11=22/-11

$\boxed {\boxed{x= - 2}}$
