8y+16=3\left(2y-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4y+8.
8y+16=6y-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2y-2.
8y+16-6y=-6
Tangohia te 6y mai i ngā taha e rua.
2y+16=-6
Pahekotia te 8y me -6y, ka 2y.
2y=-6-16
Tangohia te 16 mai i ngā taha e rua.
2y=-22
Tangohia te 16 i te -6, ka -22.
y=\frac{-22}{2}
Whakawehea ngā taha e rua ki te 2.
y=-11
Whakawehea te -22 ki te 2, kia riro ko -11.
