Kua tāruatia ki te papatopenga
9-3a-5d=m\times 5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3a-5d=m\times 5-9
Tangohia te 9 mai i ngā taha e rua.
-3a=m\times 5-9+5d
Me tāpiri te 5d ki ngā taha e rua.
-3a=5m+5d-9
He hanga arowhānui tō te whārite.
\frac{-3a}{-3}=\frac{5m+5d-9}{-3}
Whakawehea ngā taha e rua ki te -3.
a=\frac{5m+5d-9}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
a=-\frac{5d}{3}-\frac{5m}{3}+3
Whakawehe 5m-9+5d ki te -3.
9-3a-5d=m\times 5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3a-5d=m\times 5-9
Tangohia te 9 mai i ngā taha e rua.
-5d=m\times 5-9+3a
Me tāpiri te 3a ki ngā taha e rua.
-5d=5m+3a-9
He hanga arowhānui tō te whārite.
\frac{-5d}{-5}=\frac{5m+3a-9}{-5}
Whakawehea ngā taha e rua ki te -5.
d=\frac{5m+3a-9}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
d=-\frac{3a}{5}-m+\frac{9}{5}
Whakawehe 5m-9+3a ki te -5.
