Question

exercitiul 4 punctul b .Dau coroana .Cat mai repede

Answer 1

3x-4y/2x-7y=5/9⇒9(3x-4y)=5(2x-7y)⇒27x-36y=10x-35y⇒27x-10x=-35y+36y⇒

⇒17x=y⇒x/y=1/17

Answer 2

Răspuns

1/17 ;

Explicație pas cu pas:

(3x-4y)/(2x-7y) = 5/9 ;

9(3x-4y) = 5(2x-7y) ;

27x-36y = 10x-35y ;

27x-10x = 36y-35y ;

17x = y ;

x/y = 1/17 ;
