Question

solve for w: u=(v-w)/w

Answer 1

transfer the w from the denominator of the right side to the left side with multiplication
transfer the w from the right side to the left side with addition
extract w
transfer what is not w to the right side.

Answer 2

so it's w=v/u -1

Answer 3

multiply from btoh sides by w, giving us
uw = (v-w)/w * w
we get :
uw = v-w, agree ?

Answer 4

* both

Answer 5

@jaden

Answer 6

how about w=v/(u+1)

Answer 7

how you got that ?

Answer 8

u=(v-w)/w
u*w = ((v-w)/w)*w
u*w = (v-w)
u*w = v-w
uw + w = v
w(u+1) = v
w = v/(u+1)
That is correct.

Answer 9

Thank you.
