Answer 1

⛅ BUNĂ!✌

☀RĂSPUNS: x= 12, y= 8 ✔

✏fie x si y numerele căutate✨

$\bf{ \pink{x + y = 20} }$

$\bf{ \purple{y = \frac{2}{3} \times x = \frac{2x}{3} } }$

$\bf{ \blue{ x + \frac{2x}{3} = 20 } }$

✏amplificam pe x si 20 cu 3 si obținem

$\bf{ \green{ \frac{3x}{3} + \frac{2x}{3} = \frac{60}{3} } }$

$\bf{ \orange{ 3x + 2x = 60 = > 5x = 60} }$

$\bf{ \pink{x = 60 \div 5} } \\ \bf{ \pink{x = 12} }$

$\bf{ \blue{y = \frac{2 \times 12}{3} = \frac{24}{3} = 8 } }$

⚡VERIFICARE: 12+8=20 ✔

✒ Sper ca te-am ajutat!!!☺

☁ SUCCES❗

Answer 2

Răspuns:

$a + b = 20 \\ a = \frac{2}{3} \times b$

$= > \frac{2}{3} b + b = 20$

$2b + 3b = 60$

$5b = 60 = > b = 12$

$a = \frac{2}{3} \times 12 = 8$

COROANA? :)
