Kua tāruatia ki te papatopenga
y-2=\frac{2}{3}\times 9
Me whakarea ngā taha e rua ki te 9.
y-2=\frac{2\times 9}{3}
Tuhia te \frac{2}{3}\times 9 hei hautanga kotahi.
y-2=\frac{18}{3}
Whakareatia te 2 ki te 9, ka 18.
y-2=6
Whakawehea te 18 ki te 3, kia riro ko 6.
y=6+2
Me tāpiri te 2 ki ngā taha e rua.
y=8
Tāpirihia te 6 ki te 2, ka 8.
