Question

x₊2=$\frac{x}{y} 15 6$

Answer 1

Deci, ca sa ma lamuresc, $x+2 = \frac{15}{6}$.

Se rezolva foarte usor.
Aducem la acelasi numitor comun, adica 6.

$x+2 = \frac{x+2}{1} = \frac{6x+12}{6}$
$\frac{6x+12}{6}=\frac{15}{6} \Rightarrow 6x+12 = 15$
$\Rightarrow 6x = 15-12 \Rightarrow x =\frac{15-12}{6} = \frac{1}{2}$

Rezolvare alternativa:

$x+2 = \frac{15}{6} \Rightarrow x = \frac{15}{6}-2 \Rightarrow x = \frac{15}{6} - \frac{12}{6} = \frac{3}{6} = \frac{1}{2}$

Bonus: 

$x-\frac{5}{6} = 0 \Rightarrow x = 0+\frac{5}{6} \Rightarrow x = \frac{5}{6}$
