Kua tāruatia ki te papatopenga
-645p+14=-2+8-695p
Tāpirihia te 6 ki te 8, ka 14.
-645p+14=6-695p
Tāpirihia te -2 ki te 8, ka 6.
-645p+14+695p=6
Me tāpiri te 695p ki ngā taha e rua.
50p+14=6
Pahekotia te -645p me 695p, ka 50p.
50p=6-14
Tangohia te 14 mai i ngā taha e rua.
50p=-8
Tangohia te 14 i te 6, ka -8.
p=\frac{-8}{50}
Whakawehea ngā taha e rua ki te 50.
p=-\frac{4}{25}
Whakahekea te hautanga \frac{-8}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
