Question

.ajutor imi trebuie urgent ​

Answer 1

Răspuns:

4y-5 / 28 = 3y+15 / 36

<=> 36*(4y-5)=28*(3y+15) <=> 144y-180=84y+420 <=> 60y=600<=> y=10

Sper că te-am ajutat!

Answer 2

$\frac{4y - 5}{28} = \frac{3y + 15}{36}$

$36(4y - 5) = 28(3y + 15)$

$144y - 180 = 84y + 420$

$144y - 84y = 420 + 180$

$60y = 600$

$y = \frac{600}{60}$

$y = 10$
