AB-AD=0
Tangohia te AD mai i ngā taha e rua.
\left(B-D\right)A=0
Pahekotia ngā kīanga tau katoa e whai ana i te A.
A=0
Whakawehe 0 ki te B-D.
AB=AD
He hanga arowhānui tō te whārite.
\frac{AB}{A}=\frac{AD}{A}
Whakawehea ngā taha e rua ki te A.
B=\frac{AD}{A}
Mā te whakawehe ki te A ka wetekia te whakareanga ki te A.
B=D
Whakawehe AD ki te A.
