Kua tāruatia ki te papatopenga
12=3\left(y+3\right)
Tē taea kia ōrite te tāupe y ki -3 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te y+3.
12=3y+9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y+3.
3y+9=12
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3y=12-9
Tangohia te 9 mai i ngā taha e rua.
3y=3
Tangohia te 9 i te 12, ka 3.
y=\frac{3}{3}
Whakawehea ngā taha e rua ki te 3.
y=1
Whakawehea te 3 ki te 3, kia riro ko 1.
