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.

Solve 2(a + 7) = 5a - 13
timurjin [86]

Answer:

a = 9

Step-by-step explanation:

2(a + 7) = 5a - 13

We want to bring a to one side, I will choose to bring it to the right

First, expand the bracket by multiplying 2 with a + 7

2a + 14 = 5a - 13

Bring the -13 to the left by adding 13 to both sides

2a + 14 + 13 = 5a - 13 + 13

Simplify

2a + 27 = 5a

Bring the 2a to the right by subtracting 2a from both sides

2a - 2a + 27 = 5a - 2a

Simplify

27 = 5a - 2a

27 = 3a

Bring the 3 to the left by dividing both sides by 3

27÷3 = a

Simplify

a = 9
