Kua tāruatia ki te papatopenga
4375-250=2\left(-10\right)y
Whakareatia te 2 ki te -125, ka -250.
4125=2\left(-10\right)y
Tangohia te 250 i te 4375, ka 4125.
4125=-20y
Whakareatia te 2 ki te -10, ka -20.
-20y=4125
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=\frac{4125}{-20}
Whakawehea ngā taha e rua ki te -20.
y=-\frac{825}{4}
Whakahekea te hautanga \frac{4125}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
