Kua tāruatia ki te papatopenga
16a+8=2-4b
Tangohia te 4b mai i ngā taha e rua.
16a=2-4b-8
Tangohia te 8 mai i ngā taha e rua.
16a=-6-4b
Tangohia te 8 i te 2, ka -6.
16a=-4b-6
He hanga arowhānui tō te whārite.
\frac{16a}{16}=\frac{-4b-6}{16}
Whakawehea ngā taha e rua ki te 16.
a=\frac{-4b-6}{16}
Mā te whakawehe ki te 16 ka wetekia te whakareanga ki te 16.
a=-\frac{b}{4}-\frac{3}{8}
Whakawehe -6-4b ki te 16.
4b+8=2-16a
Tangohia te 16a mai i ngā taha e rua.
4b=2-16a-8
Tangohia te 8 mai i ngā taha e rua.
4b=-6-16a
Tangohia te 8 i te 2, ka -6.
4b=-16a-6
He hanga arowhānui tō te whārite.
\frac{4b}{4}=\frac{-16a-6}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{-16a-6}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
b=-4a-\frac{3}{2}
Whakawehe -6-16a ki te 4.
