Question

Solve for v in terms of s, t, and u.
S = U-t + V
V = what??

Answer 1

`v=s-u+t`

Explanation:

Hi there!

`s=u-t+v`

Our goal is to isolate v on one side of the equal sign.

Subtract u from both sides:

`s-u=u-t+v-u\\s-u=-t+v`

Add t to both sides to isolate v:

`s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t`

I hope this helps!
