Respuesta:
-15/4
Explicación paso a paso:
5/2 - n = n/3
(5 + 2n)/2 = n/3
15 + 6n = 2n
4n = -15
n = -15/4
Planteamiento:
a + 5/2 = a/3
Desarrollo:
a - a/3 = - 5/2
3a/3 - a/3 = -5/2
2a/3 = -5/2
a = (-5/2)(3/2)
a = (-5*3)/(2*2)
a = -15/4
Comprobación:
-15/4 + 5/2 = (-15/4) / 3
-15/4 + 10/4 = -15/(4*3)
-5/4 = -15/12 = -5/4
