Kua tāruatia ki te papatopenga
2x-72=158
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=158+72
Me tāpiri te 72 ki ngā taha e rua.
2x=230
Tāpirihia te 158 ki te 72, ka 230.
x=\frac{230}{2}
Whakawehea ngā taha e rua ki te 2.
x=115
Whakawehea te 230 ki te 2, kia riro ko 115.
