2 • [-3(x-3) + 5] - 2 • (3x-5) = 2(1-2x)
Aplicas propiedad distributiva en dónde hayan paréntesis/corchetes.
2 [-3x + 9 + 5] - (6x - 10) = 2 - 4x
2 [-3x + 14] - 6x + 10 = 2 - 4x
-6x + 28 - 6x + 10 = 2 - 4x
-12x + 38 = 2 - 4x
38 = 2 - 4x + 12x
38 - 2 = -4x + 12x
36 = 8x
x = 36/8 = 18/4 = 9/2
La solución a la ecuación es 9/2.
