\(\frac{x-1}{2}=\frac{y-2}{3}=\frac{z-3}{4}\)
=> \(\frac{2(x-1)}{4}=\frac{3(y-2)}{9}=\frac{z-3}{4}\)
=> \(\frac{2x-2}{4}=\frac{3y-6}{9}=\frac{z-3}{4}=\frac{2x-2+3y-6-z+3}{4+9-4}=\frac{2x+3y-z-5}{9}=\frac{50-5}{9}=5\)
=> 2x - 2 = 20 => x = 11
3y - 6 = 45 => y = 17
z - 3 = 20 => z = 23
Vậy x = 11, y = 17, z = 23
