Kua tāruatia ki te papatopenga
4ab=e+cd
Me tāpiri te cd ki ngā taha e rua.
4ba=cd+e
He hanga arowhānui tō te whārite.
\frac{4ba}{4b}=\frac{cd+e}{4b}
Whakawehea ngā taha e rua ki te 4b.
a=\frac{cd+e}{4b}
Mā te whakawehe ki te 4b ka wetekia te whakareanga ki te 4b.
4ab=e+cd
Me tāpiri te cd ki ngā taha e rua.
4ab=cd+e
He hanga arowhānui tō te whārite.
\frac{4ab}{4a}=\frac{cd+e}{4a}
Whakawehea ngā taha e rua ki te 4a.
b=\frac{cd+e}{4a}
Mā te whakawehe ki te 4a ka wetekia te whakareanga ki te 4a.
