Whakaoti mō a
a=-\frac{b}{3}+1
Whakaoti mō b
b=3-3a
Tohaina
Kua tāruatia ki te papatopenga
3a=3-b
Tangohia te b mai i ngā taha e rua.
\frac{3a}{3}=\frac{3-b}{3}
Whakawehea ngā taha e rua ki te 3.
a=\frac{3-b}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
a=-\frac{b}{3}+1
Whakawehe 3-b ki te 3.
b=3-3a
Tangohia te 3a mai i ngā taha e rua.
