180=81+3x
Tangohia te 17 i te 98, ka 81.
81+3x=180
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=180-81
Tangohia te 81 mai i ngā taha e rua.
3x=99
Tangohia te 81 i te 180, ka 99.
x=\frac{99}{3}
Whakawehea ngā taha e rua ki te 3.
x=33
Whakawehea te 99 ki te 3, kia riro ko 33.
