Question

How do you rewrite the equation for `f`: `r^2 - 5hf = Tf`?

Answer 1

`f = r^2/ (T +5h)`

Explanation:

`r^2 - 5hf = Tf`

Take the terms with variable `f` on left hand side and keep rest on right hand side of equation:

`Tf + 5hf = r^2`------- using rules of transposition.

`=>f(T +5h) = r^2`--- take `f` common from both terms.

`therefore f = r^2/ (T +5h)` ----using rules of transposition.

This is the same equation in terms of variable `f`
