Question

Calcule es valor de:x/2+8=5x/3-6

Answer 1

Respuesta:

x = 12

Explicación paso a paso:

Planteamiento:

x/2 + 8 = 5x/3  -  6

Desarrollo:

x/2  = 5x/3 -8 - 6

x/2 = 5x/3 - 14

x = 2(5x/3 - 14)

x = 2*5x/3  + 2*-14

x = 10x/3 - 28

x + 28 = 10x/3

3(x+28) = 10x

3*x + 3*28 = 10x

3x + 84 = 10x

84 = 10x - 3x

84 = 7x

x = 84/7

x = 12

Comprobación:

12/2 + 8 = 5*12/3 - 6

6 + 8 = 20 - 6 = 14
