Solutia ecuatiei x-3 totul supra x = -1 supra 2

Answer 1

x-3/x=-1/2
x-3=-1
x=3-1=2
x=2

Answer 2

$\frac{x-3}{x} = \frac{-1}{2} ~facem~prod.~mezi~si~extremi: 2x-6= -x$
trecem totul in stnga si obtinem :
$2x-6+x=0 \ \textless \ =\ \textgreater \ 3x-6=0 |+6 \ \textless \ =\ \textgreater \ 3x=6 |:3 =\ \textgreater \ x=2$
