Tohaina
Kua tāruatia ki te papatopenga
8y_{j}-1736=7j+64
Whakareatia ngā taha e rua o te whārite ki te 8.
7j+64=8y_{j}-1736
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7j=8y_{j}-1736-64
Tangohia te 64 mai i ngā taha e rua.
7j=8y_{j}-1800
Tangohia te 64 i te -1736, ka -1800.
\frac{7j}{7}=\frac{8y_{j}-1800}{7}
Whakawehea ngā taha e rua ki te 7.
j=\frac{8y_{j}-1800}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
8y_{j}-1736=7j+64
Whakareatia ngā taha e rua o te whārite ki te 8.
8y_{j}=7j+64+1736
Me tāpiri te 1736 ki ngā taha e rua.
8y_{j}=7j+1800
Tāpirihia te 64 ki te 1736, ka 1800.
\frac{8y_{j}}{8}=\frac{7j+1800}{8}
Whakawehea ngā taha e rua ki te 8.
y_{j}=\frac{7j+1800}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
y_{j}=\frac{7j}{8}+225
Whakawehe 7j+1800 ki te 8.
