Kua tāruatia ki te papatopenga
1=5\left(3x-1\right)
Tē taea kia ōrite te tāupe x ki \frac{1}{3} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 3x-1.
1=15x-5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3x-1.
15x-5=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15x=1+5
Me tāpiri te 5 ki ngā taha e rua.
15x=6
Tāpirihia te 1 ki te 5, ka 6.
x=\frac{6}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{2}{5}
Whakahekea te hautanga \frac{6}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
