12y+3=8y+27
Pahekotia te -2y me 14y, ka 12y.
12y+3-8y=27
Tangohia te 8y mai i ngā taha e rua.
4y+3=27
Pahekotia te 12y me -8y, ka 4y.
4y=27-3
Tangohia te 3 mai i ngā taha e rua.
4y=24
Tangohia te 3 i te 27, 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.
