61-90x=31
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-90x=31-61
Tangohia te 61 mai i ngā taha e rua.
-90x=-30
Tangohia te 61 i te 31, ka -30.
x=\frac{-30}{-90}
Whakawehea ngā taha e rua ki te -90.
x=\frac{1}{3}
Whakahekea te hautanga \frac{-30}{-90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -30.
