Tohaina
Kua tāruatia ki te papatopenga
9a+4b+2c=23
Pahekotia te 8a me a, ka 9a.
9a+2c=23-4b
Tangohia te 4b mai i ngā taha e rua.
9a=23-4b-2c
Tangohia te 2c mai i ngā taha e rua.
9a=23-2c-4b
He hanga arowhānui tō te whārite.
\frac{9a}{9}=\frac{23-2c-4b}{9}
Whakawehea ngā taha e rua ki te 9.
a=\frac{23-2c-4b}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
9a+4b+2c=23
Pahekotia te 8a me a, ka 9a.
4b+2c=23-9a
Tangohia te 9a mai i ngā taha e rua.
4b=23-9a-2c
Tangohia te 2c mai i ngā taha e rua.
4b=23-2c-9a
He hanga arowhānui tō te whārite.
\frac{4b}{4}=\frac{23-2c-9a}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{23-2c-9a}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
b=-\frac{c}{2}-\frac{9a}{4}+\frac{23}{4}
Whakawehe 23-9a-2c ki te 4.
