Answer:

x=3/8

Step-by-step explanation:

  1. Multiplique dentro del paréntesis por -1/2.
  2. Después de haber multiplicado le ecuación le quedará así 3x + 5/4 +1 = 9x.
  3. Ahora vamos a calcular la suma de la ecuación y quedará a 3x + 9/4 =9x.
  4. Después vamos a multiplicar ambos lados de la ecuación por 4 y quedará a 12x + 9= 36x.
  5. Luego vamos a mover la constante ( que es 9) al lado derecho y cambié su signo y quedará a 12x = 36x - 9.
  6. Después vamos agrupar los términos semejantes ( en este caso x) y quedará a -24x = -9.
  7. Finalmente vamos a dividir ambos lados de la ecuación entre -24 y la respuesta nos quedará a x = 3/8.
