Tohaina
Kua tāruatia ki te papatopenga
a\times 2=2-b\times 3
Tangohia te b\times 3 mai i ngā taha e rua.
a\times 2=2-3b
Whakareatia te -1 ki te 3, ka -3.
2a=2-3b
He hanga arowhānui tō te whārite.
\frac{2a}{2}=\frac{2-3b}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{2-3b}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
a=-\frac{3b}{2}+1
Whakawehe 2-3b ki te 2.
b\times 3=2-a\times 2
Tangohia te a\times 2 mai i ngā taha e rua.
b\times 3=2-2a
Whakareatia te -1 ki te 2, ka -2.
3b=2-2a
He hanga arowhānui tō te whārite.
\frac{3b}{3}=\frac{2-2a}{3}
Whakawehea ngā taha e rua ki te 3.
b=\frac{2-2a}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
