5 raruraru e ōrite ana ki:
\frac{ 1 }{ 30 } + \frac{ 1 }{ x } = \frac{ 1 }{ 20 }
Tohaina
Kua tāruatia ki te papatopenga
60x\times \frac{1}{30}+60=3x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 60x, arā, te tauraro pātahi he tino iti rawa te kitea o 30,x,20.
\frac{60}{30}x+60=3x
Whakareatia te 60 ki te \frac{1}{30}, ka \frac{60}{30}.
2x+60=3x
Whakawehea te 60 ki te 30, kia riro ko 2.
2x+60-3x=0
Tangohia te 3x mai i ngā taha e rua.
-x+60=0
Pahekotia te 2x me -3x, ka -x.
-x=-60
Tangohia te 60 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=60
Me whakarea ngā taha e rua ki te -1.
