Question

Solve T=L(4+RS) for R.

Answer 1

`R=(1)/(2)((T)/(L)-4)`

Step-by-step explanation

We want to solve the equation for R. This means that we want to make R the subject of the formula.

The first step is to divide both sides of the equation by L:

`\begin{gathered} T=L(4+RS) \\ \Rightarrow(T)/(L)=4+RS \end{gathered}`

Now, subtract 4 from both sides of the equation:

`(T)/(L)-4=RS`

Finally, divide both sides of the equation by S:

`\Rightarrow R=(1)/(2)((T)/(L)-4)`

That is the solution for R.
