Vreau și eu exercițiul 3 va rog repede... dau coroana

Answer 1

$\frac{2x+4}{ \frac{4}{9}+1 } = \frac{ \frac{22}{3} }{ \frac{1}{2} }$
$\frac{2x+4}{ \frac{13}{9} } = \frac{22}{3} *2$
$\frac{9(2x+4)}{13} = \frac{44}{3} ;3(18x+36)=572;18x+36= \frac{572}{3} ;18x= \frac{572}{3} -36;$
$54x=572-108;54x=464 =\ \textgreater \ x= \frac{464}{54} =\ \textgreater \ x= \frac{232}{27}$
