Kua tāruatia ki te papatopenga
80=4x\left(-2\right)
Whakareatia te 2 ki te 2, ka 4.
80=-8x
Whakareatia te 4 ki te -2, ka -8.
-8x=80
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{80}{-8}
Whakawehea ngā taha e rua ki te -8.
x=-10
Whakawehea te 80 ki te -8, kia riro ko -10.
