8y+13=12y-11
Pahekotia te 7y me 5y, ka 12y.
8y+13-12y=-11
Tangohia te 12y mai i ngā taha e rua.
-4y+13=-11
Pahekotia te 8y me -12y, ka -4y.
-4y=-11-13
Tangohia te 13 mai i ngā taha e rua.
-4y=-24
Tangohia te 13 i te -11, 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.
