2x + 2 + 3x + 1 = 4x + 8

5x + 3 = 4x + 8

5x = 4x - 5

x = -5

therefore

4(-5 + 2)

4(-3)

-12

or

4(-5 + 2)

-20 + 8

-12

either way, it’s the same.

answer: AC = -12

una fracion reducicion a su minima expresion en igual a 1/8 . si la suma de sus terminos es 72. hallar la diferencia entre ellos
Mandarinka [93]

La diferencia entre el denominador y el númerador de la fracción es:

64 - 8 = 56.

<h3>¿Como encontrar la fracción?</h3>

Tendremos una fracción de la forma:

\frac{a}{b}

Tal que:

\frac{a}{b} = \frac{1}{8}

a + b = 72

Eso es un sistema de ecuaciones

Primero, podemos reescribir la primer ecuación como:

8a = b

Ahora podemos reemplazar "b" en la segunda ecuación por "8a", así obtenemos:

a + 8a = 72\\\\9a = 72\\\\a = 72/9 = 8

Ahora podemos obtener el valor de b:

b = 8a = 8*8 = 64

La diferencia entre a y b es:

b - a = 64 - 8 = 56
