Vă rog ajutați-mă! Este urgent! Vreau poză,nu scris.

Answer 1

x/2=y/5=z/4=k⇒x=2k ; y=5k ; z=4k.
Pp. ca x=144,(3)⇒(1443-144)/9=2k⇒1299/9=2k⇒k=1299/18=72.1(6)
y=5*1299/18⇒y=360,8(3)
z=4*1299/18⇒z=288,(6)
x+y+z=1299/9+5*1299/18+4*1299/18
x+y+z=(2598+6459+5196)/18
x+y+z=14253/18
x+y+z=791.8(3)
sper sa fi rezolvat corect, in caz contrar imi cer scuze
