Question

{-5x +[-7 -2.(3x-4)+8]-43}=5

Answer 1

{ -5x +[-7-6x +8+8]-43} = 5

{-5x + 9 - 6x - 43} = 5

-11x - 34 = 5

-11 x = 5+34

-11 x = 39 (-1)

x = 39/11

x = 3,54

Answer 2

Oi

{- 5x + [ - 7 - 2(3x - 4) + 8] - 43} =5

{ - 5x + [ - 7 - 6x + 8 + 8] - 43} = 5

{ - 5x + [9 - 6x] - 43} = 5

{- 5x + 9 - 6x - 43} = 5

- 5x - 6x - 34 = 5

- 11x = 5 + 34

- 11x = 39==> ( × - 1)

11x = - 39

x = - 39/11

Ou se preferir

x = - 3,54545..
