Tohaina
Kua tāruatia ki te papatopenga
-70000t-147000=V
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-70000t=V+147000
Me tāpiri te 147000 ki ngā taha e rua.
\frac{-70000t}{-70000}=\frac{V+147000}{-70000}
Whakawehea ngā taha e rua ki te -70000.
t=\frac{V+147000}{-70000}
Mā te whakawehe ki te -70000 ka wetekia te whakareanga ki te -70000.
t=-\frac{V}{70000}-\frac{21}{10}
Whakawehe V+147000 ki te -70000.
