Tohaina
Kua tāruatia ki te papatopenga
3md=m
He hanga arowhānui tō te whārite.
\frac{3md}{3m}=\frac{m}{3m}
Whakawehea ngā taha e rua ki te 3m.
d=\frac{m}{3m}
Mā te whakawehe ki te 3m ka wetekia te whakareanga ki te 3m.
d=\frac{1}{3}
Whakawehe m ki te 3m.
3dm-m=0
Tangohia te m mai i ngā taha e rua.
\left(3d-1\right)m=0
Pahekotia ngā kīanga tau katoa e whai ana i te m.
m=0
Whakawehe 0 ki te -1+3d.
