daca 3x-2y supra 4x+y egal cu 2 supra3 atunci xsupray este....

Răspuns :

[tex] \frac{3x - 2y}{4x + y} = \frac{2}{3} [/tex]

[tex]2(4x + y) = 3(3x - 2y)[/tex]

[tex]8x + 2y = 9x - 6y[/tex]

[tex]8x - 9x = - 6y - 2y[/tex]

[tex] - x = - 8y \: | \times ( - 1)[/tex]

[tex]x = 8y \: | \div y[/tex]

[tex] \frac{x}{y} = 8[/tex]
