15x - 10 = 6x - (x + 2) + ( - x + 3)

15x - 10 = 6x - x - 2 - x + 3

15x - 10 = 4x + 1

11x = 11

x = 1 3x + [ - 5x - (x + 3)] = 8x + ( - 5x - 9)

3x + [ - 5x - x - 3] = 8x - 5x - 9

3x - 6x - 3 = 8x - 5x - 9 - 3x - 3 = 3x - 9 - 3 + 9 = 3x + 3x

6 = 6x

x = 1

16x - [3x - (6 - 9x)] = 30x + [ - (3x + 2) - (x + 3)]

16x - [3x - 6 + 9x] = 30x + [ - 3x - 2 - x - 3]

16x - 12x + 6 = 30x - 4x - 5

4x + 6 = 26x - 5

11 = 22x

x = 11 / 22 = 1 / 2.
