Tohaina
Kua tāruatia ki te papatopenga
3a=14-2b
Tangohia te 2b mai i ngā taha e rua.
\frac{3a}{3}=\frac{14-2b}{3}
Whakawehea ngā taha e rua ki te 3.
a=\frac{14-2b}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2b=14-3a
Tangohia te 3a mai i ngā taha e rua.
\frac{2b}{2}=\frac{14-3a}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{14-3a}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=-\frac{3a}{2}+7
Whakawehe 14-3a ki te 2.
