Tohaina
Kua tāruatia ki te papatopenga
8-7y-y=24
Tangohia te y mai i ngā taha e rua.
8-8y=24
Pahekotia te -7y me -y, ka -8y.
-8y=24-8
Tangohia te 8 mai i ngā taha e rua.
-8y=16
Tangohia te 8 i te 24, ka 16.
y=\frac{16}{-8}
Whakawehea ngā taha e rua ki te -8.
y=-2
Whakawehea te 16 ki te -8, kia riro ko -2.
