Solución

Ha introducido [src]
-5*cot(x) = -3*cot(x) - 2
$$- 5 \cot{\left(x \right)} = - 3 \cot{\left(x \right)} - 2$$
Solución detallada
Tenemos la ecuación
$$- 5 \cot{\left(x \right)} = - 3 \cot{\left(x \right)} - 2$$
cambiamos
$$2 - 2 \cot{\left(x \right)} = 0$$
$$\left(3 \cot{\left(x \right)} + 2\right) - 5 \cot{\left(x \right)} = 0$$
Sustituimos
$$w = \cot{\left(x \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$- 2 w = -2$$
Dividamos ambos miembros de la ecuación en -2
w = -2 / (-2)

Obtenemos la respuesta: w = 1
hacemos cambio inverso
$$\cot{\left(x \right)} = w$$
sustituimos w:
