0=0\times 9+15\left(x-0\times 9\right)
Whakareatia te 0 ki te 15, ka 0.
0=0+15\left(x-0\times 9\right)
Whakareatia te 0 ki te 9, ka 0.
0=0+15\left(x-0\right)
Whakareatia te 0 ki te 9, ka 0.
0=15\left(x-0\right)
Ko te tau i tāpiria he kore ka hua koia tonu.
15\left(x-0\right)=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x-0=0
Whakawehea ngā taha e rua ki te 15. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
x=0
Whakaraupapatia anō ngā kīanga tau.
