Question

2(x-8)-1=7 hallar la mitd de x

Answer 1

Por propiedad distributiva...

2(x-8)=2*x-2*8=2x-16

2x-16-1=7

2x-17=7

2x=17+7

2x=24

x=12

Entonces... x/2=12/2=6

Answer 2

Respuesta:

$2(x - 8) - 1 = 7$

$2x - 16 - 1 = 7$

$2x - 17 = 7$

$2x = 7 + 17$

$2x = 24$

$x = \frac{24}{2}$

$x = 12$

$\frac{x}{2} = \frac{12}{2}$

$\frac{x}{2} = 6$
