Answer 1

$Hola~~Zanahoria \\ \\ \frac{9}{19} -x= \frac{3}{7} - \frac{1}{4} \\ \\ Resolucio'n \\ \\ \frac{9-19x}{19}= \frac{3.4-1.7}{7.4} \\ \\ \frac{9-19x}{19} = \frac{12-7}{28} \\ \\ \frac{9-19x}{19} = \frac{5}{28} ~~---\ \textgreater \ multiplicamos~cruzado~tenemos: \\ \\ 28(9-19x)=19.5 \\ \\ 252-532x=95$

$-532x=95-252 \\ \\ -532x=-157 ~~--\ \textgreater \ despejamos(x)\\ \\ x= \frac{-157}{-532} \\ \\ x=0,2951...~~~---\ \textgreater \ aproximado~seria. \\ \\ \boxed{\boxed{x=0,3}}$
