Question

Solución de la ecuación 4 7b – [2 – (b 6)] – 23 = 0. Si la solución es una fracción, debes escribirla de la forma a/b. B = Respuesta.

Answer 1

4 + 7b – [2 – (b + 6)] – 23 = 0

4 + 7b – [2 – (b + 6)] – 23 = 0

4 + 7b – [2 – b – 6] – 23 = 0

4 + 7b – [2 – b – 6] – 23 = 0

4 + 7b – [–4 – b] – 23 = 0

4 + 7b – [–4 – b] – 23 = 0

4 + 7b + 4 + b – 23 = 0

4 + 8b + 4 – 23 = 0

8b – 15 = 0

8b – 15 = 0

8b = 0 + 15

8b = 15

b = 15/8

Respuesta. b = 15/8
