Answer 1

Explicație pas cu pas:

$\large \bf \dfrac{61}{35 } - \dfrac{2x}{35} = \dfrac{19}{35} + \dfrac{22}{35}$

$\large \bf \dfrac{61 - 2x}{35} = \dfrac{19 + 22}{35}$

$\large \bf 35 \cdot(61 - 2x) =35 \cdot 41 \: \: | : 35$

$\large \bf 61 - 2x =41$

$\large \bf 61 =41 + 2x$

$\large \bf 61-41 = 2x$

$\large \bf x = 20 : 2$

$\Large \boxed{ \bf x = 10}$

Answer 2

Răspuns:

61/35-2x/35=19/35+22/35

2x/35=61/35-41/35

2x/35=20/35

2x=20

x=20:2=>x=10
