Tìm x; y; z biết:
\(\frac{4}{3x-2y}=\frac{3}{2z-4x}=\frac{2}{4y-3z}\) và x + y - z = -10
Cho \(\frac{3x-2y}{4}=\frac{2z-4x}{3}=\frac{4y-3z}{2}\)
Cmr : \(\frac{x}{2}=\frac{y}{3}=\frac{z}{4}\)
Cho \(\frac{3x-2y}{4}=\frac{2z-4x}{3}=\frac{4y-3z}{2}\).Chứng minh rằng\(\frac{x}{2}=\frac{y}{3}=\frac{z}{4}\).
cho \(\frac{3x-2y}{4}=\frac{2z-4x}{3}=\frac{4y-3z}{2}\)CMR \(\frac{x}{2}=\frac{y}{3}=\frac{z}{4}\)
Tìm x, y, z biết: \(\frac{3x-2y}{37}=\frac{5y-3z}{15}=\frac{2z-5x}{2}\) và 10x - 3y - 2z= - 4
Cho \(\frac{3x-2y}{4}=\frac{2x-4x}{3}=\frac{4y-3z}{2}\)
CMR: \(\frac{x}{2}=\frac{y}{3}=\frac{z}{4}\)
Cho \(\frac{3x-2y}{4}=\frac{2x-4x}{3}=\frac{4y-3z}{2}\)
CMR: \(\frac{x}{2}=\frac{y}{3}=\frac{z}{4}\)
Cho 3x-2y/4 = 2z-4x/3 = 4y-3z/2. Chứng minh rằng: x/2 = y/3 = z/4
Cho 3x-2y/4 = 2z-4x/3 = 4y-3z/2. Chứng minh rằng: x/2 = y/3 = z/4
