Kua tāruatia ki te papatopenga
-24-12b=-24
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-12b=-24+24
Me tāpiri te 24 ki ngā taha e rua.
-12b=0
Tāpirihia te -24 ki te 24, ka 0.
b=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -12 e ōrite ki 0, me ōrite pū te b ki 0.
