✔ 最佳答案

wv - w = 2 uv
wv + 2uv = w
v (w+2u) = w
v= w/(w+2u)

w=2uv/v-1

w(v-1)=2uv

w(v)-w=2uv---------------clear D,wv=w(v)

w(v)-2uv=w

v(w-2u)=w

v=w/w-2u

w=2uv/v-1
w(v-1)=2uv
wv-w=2uv
wv-2u=w
V(w -2U) =w
v =W/(w-2u)

w = 2uv/(v - 1)
w(v - 1) = 2uv
wv - w = 2uv
wv - 2uv = w
v(w - 2u) = w
v = w/(w - 2u)
