Ta có: (3x-2y)/4 = (2z-4x)/3 = (4y-3z)/2
= (12x-8y)/16 = (6z-12x)/9 = (8y-6z)/4
= (12x-8y + 6z-12x + 8y-6z)/(16+9+4) = 0
12x - 8y = 0
<=> {6z - 12x = 0
8y - 6z = 0
x/2 = y/3
<=> {z/4 = x/2
y/3 = z/4
<=> x/2 = y/3 = z/4
Vậy<=> 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
Cho 3x-2y/4 = 2z-4x/3 = 4y-3z/2. chứng minh : x/2 = y/3 = z/4
cho 3x-2y/4 =2z-4x/3=4y-3z/2. chứng minh x/2=y/3=z/4
Cho (3x-2y)/(4)=(2z-4x)/(3)=(4y-3z)/(2)
Chứng minh (x)/(2)=(y)/(3)=(z)/(4)
cho 3x-2y/4 =2z-4x/3=4y-3z/2
chứng minh x/2 =y/3 =z/4
Cho \(\dfrac{3x-2y}{4}\)=\(\dfrac{2z-4x}{3}\)=\(\dfrac{4y-3z}{2}\)
Chứng minh rằng: \(\dfrac{x}{2}=\dfrac{y}{3}=\dfrac{z}{4}\)
5) cho \(\dfrac{3x-2y}{4}\)=\(\dfrac{2z-4x}{3}\)=\(\dfrac{4y-3z}{2}\). chứng minh rằng: \(\dfrac{x}{2}\)=\(\dfrac{y}{3}\)=\(\dfrac{z}{4}\)
cho 3x-2y/4=2z-4x/3=4y-3z/2
chung minh rang x/2=y/3=z/4
Cho 3x-2y/4=2z-4x/3=4y-3z/2. CMR : x/2=y/3=z/4
