Question

';'

Answer 1

Case I
\[\frac tA + \frac tB + \frac tC = 1\]
\[\frac 1A + \frac 1B + \frac 1C = 1\]
Case II
\[\frac tA + \frac tC = 1\]
\[\frac 2A + \frac 2C = 1\]
Case III
\[\frac tB + \frac tC = 1\]
\[\frac 3B + \frac 3C =1\]
RTF \[\frac tA + \frac tB = 1\]
seems it goes into a system of equations =_=
