Kua tāruatia ki te papatopenga
36=16\Delta t
Ko te tau i tāpiria he kore ka hua koia tonu.
16\Delta t=36
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{16\Delta t}{16\Delta }=\frac{36}{16\Delta }
Whakawehea ngā taha e rua ki te 16\Delta .
t=\frac{36}{16\Delta }
Mā te whakawehe ki te 16\Delta ka wetekia te whakareanga ki te 16\Delta .
t=\frac{9}{4\Delta }
Whakawehe 36 ki te 16\Delta .
36=16\Delta t
Ko te tau i tāpiria he kore ka hua koia tonu.
16\Delta t=36
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
16t\Delta =36
He hanga arowhānui tō te whārite.
\frac{16t\Delta }{16t}=\frac{36}{16t}
Whakawehea ngā taha e rua ki te 16t.
\Delta =\frac{36}{16t}
Mā te whakawehe ki te 16t ka wetekia te whakareanga ki te 16t.
\Delta =\frac{9}{4t}
Whakawehe 36 ki te 16t.
