Answer:

Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:

  1. <u><em>El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.</em></u>
  2. <u><em>El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.</em></u>

Step-by-step explanation:

Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:

  • 2x + 5 = 7

Seguimos el primer paso: <em>el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual</em>:

  • 2x = 7 - 5

Seguimos el segundo paso: <em>el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:</em>

  • x=\frac{7-5}{2}

Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:

  • x=\frac{2}{2}
  • x=1

<u><em>El resultado que nos daría la incógnita x sería 1</em></u>. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:

  • 2x + 5 = 7
  • 2 *(1) + 5 = 7
  • 2 + 5 = 7
  • 7 = 7

Así, identificamos que los procesos realizados fueron correctos.

Answer:

JL = 56

NK = 28

Step-by-step explanation:

Since JL  = MK

5x + 1 = 8x - 32

8x - 5x = 32 + 1

3x = 33

x = 11

so

JL = 5x + 1 = 5(11) + 1 = 55 + 1 = 56

NK = 1/2MK = 1/2JL = 56/2 = 28
