1.6p-3.2p=-12
Tangohia te 3.2p mai i ngā taha e rua.
-1.6p=-12
Pahekotia te 1.6p me -3.2p, ka -1.6p.
p=\frac{-12}{-1.6}
Whakawehea ngā taha e rua ki te -1.6.
p=\frac{-120}{-16}
Whakarohaina te \frac{-12}{-1.6} mā te whakarea i te taurunga me te tauraro ki te 10.
p=\frac{15}{2}
Whakahekea te hautanga \frac{-120}{-16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.
