Question

-15+8x-9x+24=-13-2x+7+15x

Answer 1

- 15 + 8x - 9x + 24  = - 13 - 2x + 7 + 15x

- x + 9 = 13x - 6

- x - 13x = - 6 - 9

- 14x = - 15

x = - 15/-14

x = 15/14-----Respuesta 

Answer 2

veamos:

-15 + 8x - 9x + 24 = -13 -2x + 7 + 15x

-15 + 24 + 13 - 7 = 13x + 9x - 8x

15 = 14x   ----->  x = 15/14
