Question

Daca 4X-Y supra x+2y egal 1 supra 4 aflati x supra y
VA ROG, AM NEVOIE DE AJUTOR URGENT! ​

Answer 1

Răspuns:

$\frac{4x - y}{x + 2y} = \frac{1}{4} \\ (4x - y) \times 4 = (x + 2y) \times 1 \\ 16x - 4y = 2x + 2y \\ 14x = 6y | \div y \\ 14 \frac{x}{y} = \frac{6y}{y} \\ 14 \times \frac{x}{y} = 6 \\ \frac{x}{y} = \frac{6}{14} \\ \frac{x}{y} = \frac{ 3 }{7}$
