Kua tāruatia ki te papatopenga
2a_{3}b=20\times 4
Me whakarea ngā taha e rua ki te 4.
2a_{3}b=80
Whakareatia te 20 ki te 4, ka 80.
2ba_{3}=80
He hanga arowhānui tō te whārite.
\frac{2ba_{3}}{2b}=\frac{80}{2b}
Whakawehea ngā taha e rua ki te 2b.
a_{3}=\frac{80}{2b}
Mā te whakawehe ki te 2b ka wetekia te whakareanga ki te 2b.
a_{3}=\frac{40}{b}
Whakawehe 80 ki te 2b.
2a_{3}b=20\times 4
Me whakarea ngā taha e rua ki te 4.
2a_{3}b=80
Whakareatia te 20 ki te 4, ka 80.
\frac{2a_{3}b}{2a_{3}}=\frac{80}{2a_{3}}
Whakawehea ngā taha e rua ki te 2a_{3}.
b=\frac{80}{2a_{3}}
Mā te whakawehe ki te 2a_{3} ka wetekia te whakareanga ki te 2a_{3}.
b=\frac{40}{a_{3}}
Whakawehe 80 ki te 2a_{3}.
