Question

Explicatimi si rezolvatimi varog frumos aceasta ecuatie. Varog mult. 20Puncte !!!!! COROANA pls
Aflati numerele X,Y,Z stiind ca; Xsupra2= Ysupra5= Zsupra9 si ca Z- X=35

Answer 1

$\frac{x}{2} = \frac{y}{5} = \frac{z}{9} \\ z - x = 35 = > z = 35 + x = > \frac{x}{2} = \frac{35 + x}{9} = > \\ = > 9x = 70 + 2x = > 7x = 70 = > x = 10 \\ z = 45 \\ \frac{x}{2} = \frac{y}{5} = > 2y = 50 = > y = 25$

Sper ca te-am ajutat
