Kua tāruatia ki te papatopenga
-3x-4.2=5.1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=5.1+4.2
Me tāpiri te 4.2 ki ngā taha e rua.
-3x=9.3
Tāpirihia te 5.1 ki te 4.2, ka 9.3.
x=\frac{9.3}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{93}{-30}
Whakarohaina te \frac{9.3}{-3} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-\frac{31}{10}
Whakahekea te hautanga \frac{93}{-30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
