|-3k-1+n-km|/√(k^2+1)=|-4/k-5+n+m/k|/√(1/k^2+1)这个怎么化简
|-3k-1+n-km|/√(k^2+1)=|-4/k-5+n+m/k|/√(1/k^2+1)
|-3k-1+n-km|/√(k^2+1)= |k|*|-4/k-5+n+m/k|/√(k^2+1)
|-3k-1+n-km|/√(k^2+1)=|-4-5k+nk+m|/√(k^2+1)
|-3k-1+n-km|=|-4-5k+nk+m|
-3k-1+n-km=-4-5k+nk+m,
2k+n-m+3-km-nk=0
或-3k-1+n-km|=4+5k-nk-m
8k+5-n-nk+km-m=0
