Question

Urgenttt (vreau rezolvare completa ) Daca 3x-2y supra 4x+y este egal cu 2 supra 3 atunci x supra y este egal cu ...

Answer 1

$\frac{3x-2y}{4x+y} = \frac{2}{3}$

2(4x+y)=3(3x-2y)
8x+2y=9x-6y
2y+6y=9x-8x
x=8y
x : y = 8

Answer 2

[tex]\frac{3x-2y}{4x+y}=\frac{2}{3}\\ \text{Simplificam fractia din membrul stang prin y:} \\ \frac{\frac{3x-2y}{y}}{\frac{4x+y}{y}}=\frac{3\frac{x}{y}-2}{4\frac{x}{y}+1}=\frac{2}{3}\\ 9\frac{x}{y}-6=8\frac{x}{y}+2\Rightarrow \frac{x}{y}=8[/tex]
