Question

(-0,2-x) : 0,1 = 0,4 - 5x
hallar el valor de la "X"​

Answer 1

Explicación paso a paso:

0.2=2/10

0.1=1/10

0.4=4/10

reemplazando: (

$( - \frac{2}{10} - x) - \frac{1}{10} = \frac{4}{10} - 5x \\ ( \frac{ - 2 - 10x}{10} ) - \frac{1}{10} = \frac{4 - 50x}{10 } \\ \frac{ - 3 - 10x}{10} - \frac{4 + 50x}{10} = 0 \\ - 7 - 60x = 0 \\ - 7 = 60 x \\ \frac{ - 7}{60} = x$
