Kua tāruatia ki te papatopenga
6-3p-\left(-2\right)=p-10
Hei kimi i te tauaro o 3p-2, kimihia te tauaro o ia taurangi.
6-3p+2=p-10
Ko te tauaro o -2 ko 2.
8-3p=p-10
Tāpirihia te 6 ki te 2, ka 8.
8-3p-p=-10
Tangohia te p mai i ngā taha e rua.
8-4p=-10
Pahekotia te -3p me -p, ka -4p.
-4p=-10-8
Tangohia te 8 mai i ngā taha e rua.
-4p=-18
Tangohia te 8 i te -10, ka -18.
p=\frac{-18}{-4}
Whakawehea ngā taha e rua ki te -4.
p=\frac{9}{2}
Whakahekea te hautanga \frac{-18}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
