Answer 1

Explicație pas cu pas:

Bună Andra :)

$\space$

$\color{red}\boxed{Folosim \: \frac{a}{b}=\frac{c}{d} \: dacă \: a × d = b × c}$

$\space$

$\bf\frac{2x}{3}=\frac{17}{3}$

$\bf 2x\times3=3\times17$

$\bf 2x\times3=51$

$\bf 2x=51:3$

$\bf 2x=17$

$\bf\boxed{x = \frac{17}{2} \: sau \: 8,5}$

$\space$

$\bf\frac{7x}{3}=\frac{25}{3}$

$\bf 7x\times3=3\times25$

$\bf 7x\times3=75$

$\bf 7x=75:3$

$\bf 7x=25$

$\bf\boxed{ x=\frac{25}{7}}$

$\space$

Succes :)
