Question

Make t the subject : s= [(u+v)t] / 2

Answer 1

Multiply both sides by 2/(u + v) to get..

t = 2s/(u + v)

If you are solving for u, then...

s = t(u + v)/2

Multiply both sides by 2/t to get..

2s/t = u + v

Hence, by subtracting both sides by v, we obtain:

u = (2s/t) - v

I hope this helps!

Answer 2

`s=((u+v)t)/(2) \ \ |*2\\\\ 2s=(u+v)t \ \ |:u+v\\\\ t=(2s)/(u+v)`
