Tohaina
Kua tāruatia ki te papatopenga
4p=20-3q
Tangohia te 3q mai i ngā taha e rua.
\frac{4p}{4}=\frac{20-3q}{4}
Whakawehea ngā taha e rua ki te 4.
p=\frac{20-3q}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
p=-\frac{3q}{4}+5
Whakawehe 20-3q ki te 4.
3q=20-4p
Tangohia te 4p mai i ngā taha e rua.
\frac{3q}{3}=\frac{20-4p}{3}
Whakawehea ngā taha e rua ki te 3.
q=\frac{20-4p}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
