Kua tāruatia ki te papatopenga
-9+8y=13
Whakareatia te 9 ki te -1, ka -9.
8y=13+9
Me tāpiri te 9 ki ngā taha e rua.
8y=22
Tāpirihia te 13 ki te 9, ka 22.
y=\frac{22}{8}
Whakawehea ngā taha e rua ki te 8.
y=\frac{11}{4}
Whakahekea te hautanga \frac{22}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
