Question

W=X+Xyz for z Solve the formula for the specified variable

Answer 1

The given formula is

`W=X+\text{Xyz}`

First, subtract X from each side.

`\begin{gathered} W-X=X-X+\text{Xyz} \\ W-X=\text{Xyz} \end{gathered}`

Second, divide both sides by Xy.

`\begin{gathered} (W-X)/(Xy)=\frac{\text{Xyz}}{Xy} \\ (W-X)/(Xy)=z \end{gathered}`

At last, arrange the z on the left. Therefore, the final expression is

`z=(W-X)/(Xy)`
