ANSWER

[tex] \\ \\ [/tex]

First, find the value of k.

[tex] \\ W = \frac{k}{z} \\ [/tex]

Evaluate the given values

[tex] \\ 4 = \frac{k}{6} \\ [/tex]

Multiply 6 to both sides

[tex] \\ (6)(4) = \frac{k}{6} (6) \\ [/tex]

Cancel 6 from the right side

[tex] \\ (6)(4) = \frac{k}{ \cancel{6}} ( \cancel{6}) \\ [/tex]

Multiply 6 and 4

[tex] \\ \blue{k = 24} \\ \\ [/tex]

Finding the value of z when w is 14. Use the given k value

of the first equation.

[tex] \\ W = \frac{k}{z} \\ [/tex]

Evaluate values

[tex] \\ 14 = \frac{24}{z} \\ [/tex]

Transfer 24 then divide it to 14

[tex] \\ z = \frac{24}{14} \\ [/tex]

Simplify

[tex] \\ \texttt{answer: } \implies \: \boxed{ \green{z = \frac{12}{7} }} \\ \\ \\ [/tex]
