Kua tāruatia ki te papatopenga
4t-12t-\left(-24\right)+38t-38=0
Hei kimi i te tauaro o 12t-24, kimihia te tauaro o ia taurangi.
4t-12t+24+38t-38=0
Ko te tauaro o -24 ko 24.
-8t+24+38t-38=0
Pahekotia te 4t me -12t, ka -8t.
30t+24-38=0
Pahekotia te -8t me 38t, ka 30t.
30t-14=0
Tangohia te 38 i te 24, ka -14.
30t=14
Me tāpiri te 14 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
t=\frac{14}{30}
Whakawehea ngā taha e rua ki te 30.
t=\frac{7}{15}
Whakahekea te hautanga \frac{14}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
