Question

Make x the subject! urgent help

Answer 1

`x = (h)/(b-t^2)`

Explanation:

`t^2 = b - (h)/(x)`

• First add
`(h)/(x)` to both sides:

⇒
`(h)/(x) + t^2 = b`

• Now subtract
`t^2` from both sides:

⇒
`(h)/(x) = b - t^2`

• Now multiply both sides by
`x` :

⇒
`h = x(b - t^2)`

• Next divide both sides by
`(b - t^2)` :

⇒
`(h)/(b-t^2) = x`

∴
`\boxed{x = (h)/(b-t^2)}`

Answer 2

`x = \frac{n}{b - {t}^(2) }`

Explanation:

I supposed that is a "n".

Steps as below:

`{t}^(2) = b - (n)/(x) \\ b - (n)/(x) = {t}^(2) \\ - (n)/(x) = {t}^(2) - b \\ (n)/(x) = - ( {t}^(2) - b) \\ (n)/(x) = b - {t}^(2) \\ n = x(b - {t}^(2) ) \\ x(b - {t}^(2) ) = n \\ x = \frac{n}{b - {t}^(2) }`
