a) \(\frac{1+2y}{18}=\frac{1+4y}{24}=\frac{1+6y}{6x}\)
b) \(\frac{x}{y+z+1}=\frac{y}{x+z+2}=\frac{z}{x+y-3}=x+y=z\)
Tìm x,y,z biết
a) \(\frac{x}{y+z+1}=\frac{y}{x+z+2}=\frac{z}{x+y-3}=x+y+z\)
b) \(\frac{1+2y}{18}=\frac{1+4y}{24}=\frac{1+6y}{6x}\)
a) tìm x,y,z biết rằng \(\frac{y+z+1}{x}=\frac{x+z+2}{y}=\frac{x+y-3}{z}=\frac{1}{x+y+z}\)
b) tìm x biết \(\frac{1+2y}{18}=\frac{1+4y}{24}=\frac{1+6y}{6x}\)
\(a,\frac{y+z+1}{x}=\frac{x+z+2}{y}=\frac{x+y-3}{z}=\frac{1}{x+y+z}\)
\(b,\frac{1+2y}{18}=\frac{1+4y}{24}=\frac{1+6y}{6x}\)
\(c,\frac{2x+1}{5}=\frac{3y-2}{7}=\frac{2x+3y-1}{6x}\)

Tìm x,y,z biết: \(\frac{1+2y}{18}=\frac{1+4y}{24}=\frac{1+6y}{6x}\)
Tìm x, y, z biết:
a) \(\frac{x}{2}\)=\(\frac{y}{3}\)và x.y = 54
b)\(\frac{5}{x}\)=\(\frac{3}{y}\)và x2 - y2 = 4
c) \(\frac{1+2y}{18}\)=\(\frac{1+4y}{24}\)=\(\frac{1+6y}{6x}\)
