Kua tāruatia ki te papatopenga
-27=-3x-3
Pahekotia te x me -4x, ka -3x.
-3x-3=-27
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=-27+3
Me tāpiri te 3 ki ngā taha e rua.
-3x=-24
Tāpirihia te -27 ki te 3, ka -24.
x=\frac{-24}{-3}
Whakawehea ngā taha e rua ki te -3.
x=8
Whakawehea te -24 ki te -3, kia riro ko 8.
