Solución
Solución detallada
Tenemos la ecuación
$$\cos{\left(x + \left|{x}\right| \right)} = 1$$
cambiamos
$$\cos{\left(x + \left|{x}\right| \right)} - 1 = 0$$
$$\cos{\left(x + \left|{x}\right| \right)} - 1 = 0$$
Sustituimos
$$w = \cos{\left(x + \left|{x}\right| \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = 1$$
Obtenemos la respuesta: w = 1
hacemos cambio inverso
$$\cos{\left(x + \left|{x}\right| \right)} = w$$
sustituimos w:
$$\cos{\left(x + \left|{x}\right| \right)} = 1$$
cambiamos
$$\cos{\left(x + \left|{x}\right| \right)} - 1 = 0$$
$$\cos{\left(x + \left|{x}\right| \right)} - 1 = 0$$
Sustituimos
$$w = \cos{\left(x + \left|{x}\right| \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w = 1$$
Obtenemos la respuesta: w = 1

$$\cos{\left(x + \left|{x}\right| \right)} = w$$
sustituimos w:
