Tim x , y , z biet: x /y+z+1 = y/ z+x+2 = z/ x+y−3 =x+y+z Cach lam ho minh voi
tim x,y,z biet; x/z+y+1=y/x+z+1=x+y-2=x+y+z
Tim x , y , z biet:
\(\frac{x}{y+z+1}=\frac{y}{z+x+2}=\frac{z}{x+y+3}=x+y+z\)
tim x;y;z biet x+y+z =1+2+3
vàx/1=y/2=z/3
tim x,y,z biet: \(\frac{x+z+2}{y}=\frac{y+z+1}{x}=x+y+3=\frac{1}{x+y+z}\)
Tim x,y,z biet
X+y+2005/z=y+z-2006/x=x+z+1/y=2/x+y+z
Tim ba so x, y, z biet \(\frac{y+z+1}{x}=\frac{x+ z+2}{y}=\frac{x+y-3}{z}=\frac{1}{x+y+z}\)
biet rang x/y+z+1=y/x+z+1=z/x+y-2=x+y+z
tim x. y.z
tim x,y,z biet
\(\frac{x}{y+z+1}=\frac{y}{z+x+1}=\frac{z}{x+y-2}=x+y+z\)
