Kua tāruatia ki te papatopenga
30=2x-6
Pahekotia te x me x, ka 2x.
2x-6=30
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=30+6
Me tāpiri te 6 ki ngā taha e rua.
2x=36
Tāpirihia te 30 ki te 6, ka 36.
x=\frac{36}{2}
Whakawehea ngā taha e rua ki te 2.
x=18
Whakawehea te 36 ki te 2, kia riro ko 18.
