Kua tāruatia ki te papatopenga
3=\frac{1}{3}y-4
Tangohia te 2 i te 5, ka 3.
\frac{1}{3}y-4=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{1}{3}y=3+4
Me tāpiri te 4 ki ngā taha e rua.
\frac{1}{3}y=7
Tāpirihia te 3 ki te 4, ka 7.
y=7\times 3
Me whakarea ngā taha e rua ki te 3, te tau utu o \frac{1}{3}.
y=21
Whakareatia te 7 ki te 3, ka 21.
