5 raruraru e ōrite ana ki:
\frac{ 1 }{ 85 } = \frac{ 1 }{ 90 } + \frac{ 1 }{ x }
Tohaina
Kua tāruatia ki te papatopenga
18x=1530x\times \frac{1}{90}+1530
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 1530x, arā, te tauraro pātahi he tino iti rawa te kitea o 85,90,x.
18x=\frac{1530}{90}x+1530
Whakareatia te 1530 ki te \frac{1}{90}, ka \frac{1530}{90}.
18x=17x+1530
Whakawehea te 1530 ki te 90, kia riro ko 17.
18x-17x=1530
Tangohia te 17x mai i ngā taha e rua.
x=1530
Pahekotia te 18x me -17x, ka x.
