Question

Adică x+2 supra x+10 =1 supra 3 va rog?

Answer 1

x+2/x+10 = 1/3 
3(x+2) = x+10
3x+6=x+10
3x - x = 10 - 6
2x = 4
x = 4:2 
x= 2  

Answer 2

    
[tex]\displaystyle \bf\\ \frac{x+2}{x+10} = \frac{1}{3} \\\\ \text{Egalam produsul mezilor cu produsul extremilor.}\\\\ 3(x+2) = 1(x+10)\\\\ 3x + 6 = x + 10\\\\ 3x - x = 10 - 6\\\\ 2x = 4\\\\ x = \frac{4}{2} = \boxed{\bf 2}[/tex]
