Question

ayuda porfavor es que no entiendo (2/r) + (5/3r) =1

Answer 1

2/r+5/3r =1,r
6+5/3r=1
3r=11
R=11/3

Answer 2

Hola ...........

$\frac{2}{r} + \frac{5}{3r} =1$

$\frac{2.3r+r.5}{3r.r} =1$

$\frac{6r+5r}{3r^{2} } =1$

$11r=3r^{2}$

$\frac{11r}{r}=3r$

$\frac{11}{3}=r$

Rpta: $\frac{11}{3}$

Suerte y saludos !!
