Thread: Changing the subject of a Formula

1. Changing the subject of a Formula

Hi there having an issue with this question, could anyone show the steps involved on how to changing the subject of a formula

a) Make U the subject :- s = 1/2 (u+v) t

b) Make K the subject :- d = √6M/Kx+1 (Square root is on the whole fraction)

2. Transposing:

$S=\dfrac{u+v}{2}\times~t$

Divide both sides by t:

$\dfrac{S}{t} = \dfrac{u+v}{2}$

Multiply both sides by 2:

$\dfrac{2S}{t}=u+v$

Subtract v from both sides:

$u=\dfrac{2S}{t}-v$

Post an attempt at b) yourself using similar methods; start by squaring both sides.

I uploaded a picture with proper formula in it.

I think its right but not 100% sure.
