Answer 1

Given that:

`G=(d)/(1-u)`

- we cross multiply as follows:

`G*(1-u)=d`

- we divide both sides by G, as follows:

`\begin{gathered} (G*(1-u))/(G)=(d)/(G) \\ \end{gathered}`
`1-u=(d)/(G)`

- Subtract 1 from both sides of the equation:

`1-u-1=(d)/(G)-1`
`-u=(d)/(G)-1`

- multiply both sides of the equation by -1, as follows:

`-u*-1=((d)/(G)-1)*-1`
`u=-(d)/(G)+1`

Therefore, we have that:

`u=1-(d)/(G)`

or:

`u=(G-d)/(G)`
