Question

Buna ziua ! Ma puteti ajuta cu un exercitiu la matematica?
Am atasat poza.

Answer 1

$\frac{x}{y} = \frac{3}{14}\rightarrow y= \frac{14x}{3} \\ x+y=34 \leftrightarrow x+ \frac{14x}{3}=34\ \ \ \ /\cdot3 \\ 3x+14x=102 \\ 17x=102 \\ x=102:17=6 \\ y=34-6=28 \\ \frac{x+y}{y}= \frac{34}{28}= \frac{17}{14}$
