Suppose y varies directly with x and inversely with z. If y = 14 when x = 7 and z = 3, what is x when y = 3 and z = 8? Use the step-by-step process you learned to solve this problem. with Answers. Step 1: Set up the correct type of variation equation.
y =
✔ kx/z
Step 2: Determine the constant of variation.
k =

⇒ 6
Step 3: Determine the missing value.
When y = 3 and z = 8, x =

⇒ 4.
