Tohaina
Kua tāruatia ki te papatopenga
0s+1=7+45s
Whakareatia te 0 ki te 5, ka 0.
0+1=7+45s
Ko te tau i whakarea ki te kore ka hua ko te kore.
1=7+45s
Tāpirihia te 0 ki te 1, ka 1.
7+45s=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
45s=1-7
Tangohia te 7 mai i ngā taha e rua.
45s=-6
Tangohia te 7 i te 1, ka -6.
s=\frac{-6}{45}
Whakawehea ngā taha e rua ki te 45.
s=-\frac{2}{15}
Whakahekea te hautanga \frac{-6}{45} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
