8y-4y-\left(-16\right)=40
Hei kimi i te tauaro o 4y-16, kimihia te tauaro o ia taurangi.
8y-4y+16=40
Ko te tauaro o -16 ko 16.
4y+16=40
Pahekotia te 8y me -4y, ka 4y.
4y=40-16
Tangohia te 16 mai i ngā taha e rua.
4y=24
Tangohia te 16 i te 40, ka 24.
y=\frac{24}{4}
Whakawehea ngā taha e rua ki te 4.
y=6
Whakawehea te 24 ki te 4, kia riro ko 6.
