The Attempt at a Solution
basically i would rewrite the equation as,
(x/l)/(mb + nc - la) = (y/m)/(nc + la - mb) = (z/n)/(la + mb - nc)
upon adding,i get
(x/l + y/m + z/n)/(la+mb+nc)
but what they provided is,
(y/m + z/n)/2la = two similar expressions
==> (ny + mz)/a = (lz + nx)/b = (mx + ly)/c
i did not understand how did they get that.
since this is a proof problem i only used the "3. The Attempt at a Solution " section.
