Kua tāruatia ki te papatopenga
15=5\left(x+1\right)
Tē taea kia ōrite te tāupe x ki -1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+1.
15=5x+5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+1.
5x+5=15
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=15-5
Tangohia te 5 mai i ngā taha e rua.
5x=10
Tangohia te 5 i te 15, ka 10.
x=\frac{10}{5}
Whakawehea ngā taha e rua ki te 5.
x=2
Whakawehea te 10 ki te 5, kia riro ko 2.
