0=-12x+12
Pahekotia te -4x me -8x, ka -12x.
-12x+12=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-12x=-12
Tangohia te 12 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-12}{-12}
Whakawehea ngā taha e rua ki te -12.
x=1
Whakawehea te -12 ki te -12, kia riro ko 1.
