Question

Dacă x supra y egal cu 2 supra 3 atunci 3x plus y supra 6 x minus y egal cu 1. VĂ ROG FRUMOS!!!​

Answer 1

$\displaystyle{ \frac{x}{y} = \frac{2}{3} \longrightarrow 2y = 3x}$

$\displaystyle{ \frac{3x+y}{6x-y} = 1 }$

$\displaystyle{ \frac{2y + y}{4y-y}= 1 }$

$\displaystyle{ \frac{3y}{3y} = 1 }$

1 = 1
