✔ 最佳答案
wv - w = 2 uvwv + 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(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(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)
w(v - 1) = 2uv
wv - w = 2uv
wv - 2uv = w
v(w - 2u) = w
v = w/(w - 2u)
