Tohaina
Kua tāruatia ki te papatopenga
3x=19-2z
Tangohia te 2z mai i ngā taha e rua.
\frac{3x}{3}=\frac{19-2z}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{19-2z}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2z=19-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{2z}{2}=\frac{19-3x}{2}
Whakawehea ngā taha e rua ki te 2.
z=\frac{19-3x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
