Answer 1

Răspuns:

x+3/5=x+6/10

produsul mezilor este egal cu produsul extremilor

10(x+3)=5(x+6)

10x+30=5x+30

10x=5x |:5

2x=x=> x=0

Answer 2

$\it \it \dfrac{^{2)}x+3}{\ 5}=\it \dfrac{x+6}{10} \Rightarrow \dfrac{2x+6}{10}=\dfrac{x+6}{10} \Rightarrow 2x+6=x+6\Rightarrow 2x-x=6-6 \Rightarrow\\ \\ \\ \Rightarrow x=0$
