Tohaina
Kua tāruatia ki te papatopenga
2A-5C=83-7B
Tangohia te 7B mai i ngā taha e rua.
2A=83-7B+5C
Me tāpiri te 5C ki ngā taha e rua.
2A=83+5C-7B
He hanga arowhānui tō te whārite.
\frac{2A}{2}=\frac{83+5C-7B}{2}
Whakawehea ngā taha e rua ki te 2.
A=\frac{83+5C-7B}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
7B-5C=83-2A
Tangohia te 2A mai i ngā taha e rua.
7B=83-2A+5C
Me tāpiri te 5C ki ngā taha e rua.
7B=83+5C-2A
He hanga arowhānui tō te whārite.
\frac{7B}{7}=\frac{83+5C-2A}{7}
Whakawehea ngā taha e rua ki te 7.
B=\frac{83+5C-2A}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
