Question

Make y the subject in the formula
v = u2 – t

Answer 1

(you may mean: solve for "u")

Answer:
`t=u^2-v`

Explanation:

`v=u^2-t`

`\mathrm{Add\:}t\mathrm{\:to\:both\:sides}:`

`v+t=u^2-t+t`

`\mathrm{Simplify}`:

`v+t=u^2`

`\mathrm{Subtract\:}v\mathrm{\:from\:both\:sides}:`

`v+t-v=u^2-v`

`\mathrm{Simplify}:`

`t=u^2-v < -answer~;3`
