Question 1016440
The given conditions are impossible. Assuming x, y, and z are nonzero, this would imply:


*[tex \large \frac{x}{y} \times \frac{y}{z} \times \frac{z}{x} = 6 \times 7 \times 9 = 378]


However the left-hand side equals 1. If any of x, y, or z is zero, then one of the fractions is undefined in value.
