Question

Make R the subject of the formula in E = [W(R - r)] /[2RP]​

Answer 1

`R =\cfrac{Wr}{W - 2EP}`

=================

Given formula:

• 
  `E = [W(R - r)] /[2RP]`

Make R the subject in following steps:

• 
  `2ERP = WR - Wr` Multiply both sides by 2RP

• 
  `WR - 2ERP = Wr` Isolate terms with R

• 
  `R(W - 2EP) =Wr` Factor out R

• 
  `R =\cfrac{Wr}{W - 2EP}` Divide both sides by (W - 2EP)
