Given: open vertical bar table row p b c row a q c row a b r end table close vertical bar equals 0
A p p l y i n g space R subscript 2 rightwards arrow R subscript 2 minus R subscript 1 space space a n d space space R subscript 3 rightwards arrow R subscript 3 minus R subscript 1
rightwards double arrow open vertical bar table row p b c row cell a minus p end cell cell q minus b end cell 0 row cell a minus p end cell 0 cell r minus c end cell end table close vertical bar equals 0
rightwards double arrow c open vertical bar table row cell a minus p end cell cell q minus b end cell row cell a minus p end cell 0 end table close vertical bar minus 0 plus open parentheses r minus c close parentheses open vertical bar table row p b row cell a minus p end cell cell q minus b end cell end table close vertical bar equals 0
rightwards double arrow negative c open parentheses a minus p close parentheses open parentheses q minus b close parentheses plus open parentheses r minus c close parentheses open square brackets p open parentheses q minus b close parentheses minus b open parentheses a minus p close parentheses close square brackets equals 0

rightwards double arrow negative c open parentheses a minus p close parentheses open parentheses q minus b close parentheses plus p open parentheses r minus c close parentheses open parentheses q minus b close parentheses minus b open parentheses r minus c close parentheses open parentheses a minus p close parentheses equals 0

rightwards double arrow fraction numerator c over denominator r minus c end fraction plus fraction numerator p over denominator p minus a end fraction plus fraction numerator b over denominator q minus b end fraction equals 0
