Ajutati-ma ,dau coroana​,vaaaa rogggggggg

Answer 1

Răspuns:   c)   4/7

Explicație pas cu pas:

( 3 x - 2 y ) / ( 2 x + 3 y ) = 1/2

2 × ( 3 x - 2 y ) = 2 x + 3 y → produsul mezilor = produsul extremilor

6 x - 4 y = 2 x + 3 y

6 x - 2 x = 3 y + 4 y

4 x = 7 y   ⇒   y/x = 4/7

Answer 2

(3x-2y)/(2x+3y)=1/2

2(3x-2y)=2x+3y

6x-4y=2x+3y

6x-2x=3y+4y

4x=7y

y/x=4/7

c) 4/7
