Kua tāruatia ki te papatopenga
6r=-67-5s
Tangohia te 5s mai i ngā taha e rua.
6r=-5s-67
He hanga arowhānui tō te whārite.
\frac{6r}{6}=\frac{-5s-67}{6}
Whakawehea ngā taha e rua ki te 6.
r=\frac{-5s-67}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
5s=-67-6r
Tangohia te 6r mai i ngā taha e rua.
5s=-6r-67
He hanga arowhānui tō te whārite.
\frac{5s}{5}=\frac{-6r-67}{5}
Whakawehea ngā taha e rua ki te 5.
s=\frac{-6r-67}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
