Respuesta:

$5x = 8x - 15 \\ 5x - 8x = - 15 \\ - 3x = - 15 \\ x = \frac{ - 15}{ - 3} \\ x = 5$

$y - 5 = 3y - 25 \\ y - 3y = - 25 + 5 \\ - 2y = - 20 \\ y = 10$

$8x - 4 + 3x = 7x + x + 14 \\ 11x - 4 = 8x + 14 \\ 11x - 8x = 14 + 4 \\ 3x = 18 \\ x = 6$

$15x - 10 = 6x - (x + 2) + ( - x + 3) \\ 15x - 10 = 6x - x - 2 - x + 3 \\ 15x - 4x = 1 + 10 \\ 11x = 11 \\ x = 1$

$(5 - 3x) - ( - 4x + 6) = (8x + 11) - (3x - 6) \\ 5 - 3x + 4x - 6 = 8x + 11 - 3x + 6 \\ x - 1 = 5x + 17 \\ x - 5x = 17 + 1 \\ - 4x = 18 \\ x = \frac{18}{ - 4} \\ x = \frac{9}{ - 2}$

$15x + ( - 6x + 5) - 2 - ( - x + 3) = - (7x + 23) - x + (3 - 2x) \\ 15x - 6x + 5 - 2 + x - 3 = - 7x - 23 - x + 3 - 2x \\ 10x = - 10x - 20 \\ 10x + 10x = - 20 \\ 20x = - 20 \\ x = \frac{ - 20}{20} \\ x = - 1$
