Tohaina
Kua tāruatia ki te papatopenga
2m+3=n+7
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2m=n+7-3
Tangohia te 3 mai i ngā taha e rua.
2m=n+4
Tangohia te 3 i te 7, ka 4.
\frac{2m}{2}=\frac{n+4}{2}
Whakawehea ngā taha e rua ki te 2.
m=\frac{n+4}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
m=\frac{n}{2}+2
Whakawehe n+4 ki te 2.
n=2m+3-7
Tangohia te 7 mai i ngā taha e rua.
n=2m-4
Tangohia te 7 i te 3, ka -4.
