Question

15 puntos si me responden esta ecuación:
A) 30 - x ÷8=25

Answer 1

$30 - \frac{x}{8} = 25$
$240 - x = 200$
$- x = 200 -240$
$- x = 40$
$x = 40$

Answer 2

$30 - \frac{x}{8} = 25$

$30 = 25 + \frac{x}{8}$

$30 - 25 = \frac{x}{8}$

$5 = \frac{x}{8}$

$5 * 8 = x$

x = 40

Comprobando :

$30 - \frac{40}{8} = 30 - 5 = 25$
