Answer
The statement is true.
Work Step by Step
Solve for $z$ in the given equation by doing the following steps:
(1) Multiply $z$ to both sides.
$z \cdot y = z \cdot \dfrac{kx}{z}
\\yz = kx$
(2) Divide by $y$ on both sides of the equation:
$\dfrac{yz}{y} = \dfrac{kx}{y}
\\z=\dfrac{kx}{y}$
Thus, the given statement is true.
