Tohaina
Kua tāruatia ki te papatopenga
4a-2b=-2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4a=-2+2b
Me tāpiri te 2b ki ngā taha e rua.
4a=2b-2
He hanga arowhānui tō te whārite.
\frac{4a}{4}=\frac{2b-2}{4}
Whakawehea ngā taha e rua ki te 4.
a=\frac{2b-2}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
a=\frac{b-1}{2}
Whakawehe -2+2b ki te 4.
4a-2b=-2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2b=-2-4a
Tangohia te 4a mai i ngā taha e rua.
-2b=-4a-2
He hanga arowhānui tō te whārite.
\frac{-2b}{-2}=\frac{-4a-2}{-2}
Whakawehea ngā taha e rua ki te -2.
b=\frac{-4a-2}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
b=2a+1
Whakawehe -2-4a ki te -2.
