5 raruraru e ōrite ana ki:
\frac { 2 } { x } + \frac { 1 } { 3 } = \frac { 5 } { x }
Tohaina
Kua tāruatia ki te papatopenga
3\times 2+3x\times \frac{1}{3}=3\times 5
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 3x, arā, te tauraro pātahi he tino iti rawa te kitea o x,3.
6+3x\times \frac{1}{3}=3\times 5
Whakareatia te 3 ki te 2, ka 6.
6+x=3\times 5
Me whakakore te 3 me te 3.
6+x=15
Whakareatia te 3 ki te 5, ka 15.
x=15-6
Tangohia te 6 mai i ngā taha e rua.
x=9
Tangohia te 6 i te 15, ka 9.
