Question

15x -9 +{-5x +12 -[3x-5 -(15 + x)]} = -11x +14 -{2x -3 +[-6x+(7-3x)}​

Answer 1

Respuesta:

x = -13/10

Explicación paso a paso:

15x -9 +{-5x +12 -[3x-5 -(15 + x)]} = -11x +14 -{2x -3 +[-6x+(7-3x)]}​

15x -9 +{-5x +12 -[3x-5 -15 + x]} = -11x +14 -{2x -3 +[-6x+7-3x]}​

15x -9 +{-5x +12 -[4x-20]} = -11x +14 -{2x -3 +[-9x+7]}​

15x -9 +{-5x +12 -4x + 20} = -11x +14 -{2x -3 - 9x + 7}​

15x -9 +{-9x + 32} = -11x +14 -{-7x+4}​

15x -9 - 9x + 32} = -11x +14 +7x-4

6x + 23 = -4x + 10

6x + 4x = 10 - 23

10x = -13

x = -13/10
