Whakaoti mō a
a=\frac{2b+2d+1}{3}
Whakaoti mō b
b=\frac{3a}{2}-d-\frac{1}{2}
Tohaina
Kua tāruatia ki te papatopenga
2b+2d=3a-1
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te b+d.
3a-1=2b+2d
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3a=2b+2d+1
Me tāpiri te 1 ki ngā taha e rua.
\frac{3a}{3}=\frac{2b+2d+1}{3}
Whakawehea ngā taha e rua ki te 3.
a=\frac{2b+2d+1}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2b+2d=3a-1
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te b+d.
2b=3a-1-2d
Tangohia te 2d mai i ngā taha e rua.
2b=3a-2d-1
He hanga arowhānui tō te whārite.
\frac{2b}{2}=\frac{3a-2d-1}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{3a-2d-1}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=\frac{3a}{2}-d-\frac{1}{2}
Whakawehe 3a-1-2d ki te 2.
