y = 3x / ( 5 + 2x)
ok im stuck lol
im at : 2y + 5xy = 3x
Hello,
You messed up the factors !
$\displaystyle y=\frac{3x}{5+2x}$
multiply both sides by $\displaystyle 5+2x$ :
$\displaystyle y(5+2x)=3x$
develop :
$\displaystyle 5y+2xy=3x$
now group the terms where x appears :
$\displaystyle 5y=3x-2xy$
factor :
$\displaystyle 5y=x(3-2y)$
hence $\displaystyle x=\dots$
