Kua tāruatia ki te papatopenga
x\times 12=15\times 15
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 15x, arā, te tauraro pātahi he tino iti rawa te kitea o 15,x.
x\times 12=225
Whakareatia te 15 ki te 15, ka 225.
x=\frac{225}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{75}{4}
Whakahekea te hautanga \frac{225}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
