55000+500y-2000y=62000
Tangohia te 2000y mai i ngā taha e rua.
55000-1500y=62000
Pahekotia te 500y me -2000y, ka -1500y.
-1500y=62000-55000
Tangohia te 55000 mai i ngā taha e rua.
-1500y=7000
Tangohia te 55000 i te 62000, ka 7000.
y=\frac{7000}{-1500}
Whakawehea ngā taha e rua ki te -1500.
y=-\frac{14}{3}
Whakahekea te hautanga \frac{7000}{-1500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 500.
