Kua tāruatia ki te papatopenga
3\left(3y+1\right)=3y-1
Tē taea kia ōrite te tāupe y ki \frac{1}{3} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3\left(3y-1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3y-1,3.
9y+3=3y-1
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3y+1.
9y+3-3y=-1
Tangohia te 3y mai i ngā taha e rua.
6y+3=-1
Pahekotia te 9y me -3y, ka 6y.
6y=-1-3
Tangohia te 3 mai i ngā taha e rua.
6y=-4
Tangohia te 3 i te -1, ka -4.
y=\frac{-4}{6}
Whakawehea ngā taha e rua ki te 6.
y=-\frac{2}{3}
Whakahekea te hautanga \frac{-4}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
