Linear Equation
14 = -2x+12
Tohaina
Kua tāruatia ki te papatopenga
-2x+12=14
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=14-12
Tangohia te 12 mai i ngā taha e rua.
-2x=2
Tangohia te 12 i te 14, ka 2.
x=\frac{2}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-1
Whakawehea te 2 ki te -2, kia riro ko -1.
