Tohaina
Kua tāruatia ki te papatopenga
5a+c=17-3b
Tangohia te 3b mai i ngā taha e rua.
5a=17-3b-c
Tangohia te c mai i ngā taha e rua.
5a=17-c-3b
He hanga arowhānui tō te whārite.
\frac{5a}{5}=\frac{17-c-3b}{5}
Whakawehea ngā taha e rua ki te 5.
a=\frac{17-c-3b}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
3b+c=17-5a
Tangohia te 5a mai i ngā taha e rua.
3b=17-5a-c
Tangohia te c mai i ngā taha e rua.
3b=17-c-5a
He hanga arowhānui tō te whārite.
\frac{3b}{3}=\frac{17-c-5a}{3}
Whakawehea ngā taha e rua ki te 3.
b=\frac{17-c-5a}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
