tìm x;y;z nếu
\(x+y+z=\frac{x}{y+z-2}=\frac{y}{z+x-3}=\frac{z}{x+y+5}\)
Tìm x , y , z nếu :
a)\(\frac{x+y+1}{x}=\frac{x+z+2}{y}=\frac{x+y-3}{z}=\frac{1}{x+y+z}\)
b)\(\frac{x-1}{2}=\frac{y-2}{3}=\frac{z-3}{4}\)và 2x+3y-z=50
Tìm x,y,z \(\frac{y+z+3}{x}=\frac{x+z+2}{y}=\frac{x+y-5}{z}=\frac{1}{x+y+z}\)
Tìm x,y,z biết
