Kua tāruatia ki te papatopenga
150=-4x-6
Whakareatia te -2 ki te 2, ka -4.
-4x-6=150
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-4x=150+6
Me tāpiri te 6 ki ngā taha e rua.
-4x=156
Tāpirihia te 150 ki te 6, ka 156.
x=\frac{156}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-39
Whakawehea te 156 ki te -4, kia riro ko -39.
