If: (x/l)/(mb+nc-ax) = (y/M)/(nc+la-mb) = (z/n)/(la+mb-nc)
The next line in the book says....
1. (ny+mz)/a = 2. (lz+nx)/b = 3. (mx+ly)/c
I dont understand how they got to this point...
My guess is that they added them seperatly then simplifyed somehow?
This is what I came up with after adding them....
The Attempt at a Solution
1. (y/m + z/n)/2la = 2. (z/n+x/l)/2mb = 3. (y/m+x/l)/2nc
it looks like in 1. they cross mult in the numerator whish would then give us (ny+mz/nm)/2la = (ny+mz)/(nm)2la.... but where did the nm2l go in the denominator?
