Tohaina
Kua tāruatia ki te papatopenga
-2f=5.7+0.9
Me tāpiri te 0.9 ki ngā taha e rua.
-2f=6.6
Tāpirihia te 5.7 ki te 0.9, ka 6.6.
f=\frac{6.6}{-2}
Whakawehea ngā taha e rua ki te -2.
f=\frac{66}{-20}
Whakarohaina te \frac{6.6}{-2} mā te whakarea i te taurunga me te tauraro ki te 10.
f=-\frac{33}{10}
Whakahekea te hautanga \frac{66}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
