Tohaina
Kua tāruatia ki te papatopenga
7AD=5AB
Tē taea kia ōrite te tāupe A ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 7AB, arā, te tauraro pātahi he tino iti rawa te kitea o AB,7.
7AD-5AB=0
Tangohia te 5AB mai i ngā taha e rua.
\left(7D-5B\right)A=0
Pahekotia ngā kīanga tau katoa e whai ana i te A.
A=0
Whakawehe 0 ki te 7D-5B.
A\in \emptyset
Tē taea kia ōrite te tāupe A ki 0.
7AD=5AB
Tē taea kia ōrite te tāupe B ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 7AB, arā, te tauraro pātahi he tino iti rawa te kitea o AB,7.
5AB=7AD
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{5AB}{5A}=\frac{7AD}{5A}
Whakawehea ngā taha e rua ki te 5A.
B=\frac{7AD}{5A}
Mā te whakawehe ki te 5A ka wetekia te whakareanga ki te 5A.
B=\frac{7D}{5}
Whakawehe 7AD ki te 5A.
B=\frac{7D}{5}\text{, }B\neq 0
Tē taea kia ōrite te tāupe B ki 0.
