Kua tāruatia ki te papatopenga
18x+5=B
Tangohia te 12 i te 17, ka 5.
B=18x+5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
18x+5=B
Tangohia te 12 i te 17, ka 5.
18x=B-5
Tangohia te 5 mai i ngā taha e rua.
\frac{18x}{18}=\frac{B-5}{18}
Whakawehea ngā taha e rua ki te 18.
x=\frac{B-5}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
