Tohaina
Kua tāruatia ki te papatopenga
3z=-1-y
Tangohia te y mai i ngā taha e rua.
3z=-y-1
He hanga arowhānui tō te whārite.
\frac{3z}{3}=\frac{-y-1}{3}
Whakawehea ngā taha e rua ki te 3.
z=\frac{-y-1}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-1-3z
Tangohia te 3z mai i ngā taha e rua.
