Linear Equation
245 = 161 - 24 r
Tohaina
Kua tāruatia ki te papatopenga
161-24r=245
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-24r=245-161
Tangohia te 161 mai i ngā taha e rua.
-24r=84
Tangohia te 161 i te 245, ka 84.
r=\frac{84}{-24}
Whakawehea ngā taha e rua ki te -24.
r=-\frac{7}{2}
Whakahekea te hautanga \frac{84}{-24} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
