Kua tāruatia ki te papatopenga
-0.06x+3.3=50
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-0.06x=50-3.3
Tangohia te 3.3 mai i ngā taha e rua.
-0.06x=46.7
Tangohia te 3.3 i te 50, ka 46.7.
x=\frac{46.7}{-0.06}
Whakawehea ngā taha e rua ki te -0.06.
x=\frac{4670}{-6}
Whakarohaina te \frac{46.7}{-0.06} mā te whakarea i te taurunga me te tauraro ki te 100.
x=-\frac{2335}{3}
Whakahekea te hautanga \frac{4670}{-6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
