Question

U=F(r+B) solve for r

Answer 1

The value of r =
`(U-FB)/(F)`

Explanation:

We have,

U = F(r + B)

To find, the value of r = ?

∴ U = F(r + B)

Dividing both sides by F, we get

`(U )/(F)=(F(r+B) )/(F)`

⇒
`(U )/(F)` = r + B

⇒ r + B =
`(U )/(F)`

⇒ r =
`(U )/(F)` - B

⇒ r =
`(U-FB)/(F)`

∴ The value of r =
`(U-FB)/(F)`
