Question

Помгите$\frac{x}{y}$

Answer 1

Ответ:

x=675/46

y=420/23

Пошаговое объяснение:

вроде так.

(x+v)/15-(x-v)/3=1

(2x-v)/6-(3x+2v)/3=-25

(2x)/5-(4v)/15=1

(2x-v)/6-(3x+2v)/3=-25

(2x)/5-(4v)/15=1

-(2x)/3-(5v)/6=-25

(2x)/5=(4v+15)/15

-(2x)/3-(5v)/6=-25

x=(4v+15)/6

-(2x)/3-(5v)/6=-25

x=(4v+15)/6

(-4v-15)/9-(5v)/6=-25

x=(4v+15)/6

-(23v)/18-5/3=-25

x=(4v+15)/6

-(23v)/18=-70/3

x=(4v+15)/6

y=420/23

x=675/46

y=420/23
