Kua tāruatia ki te papatopenga
8x-10=2x-1
Whakareatia ngā taha e rua o te whārite ki te 2.
8x-10-2x=-1
Tangohia te 2x mai i ngā taha e rua.
6x-10=-1
Pahekotia te 8x me -2x, ka 6x.
6x=-1+10
Me tāpiri te 10 ki ngā taha e rua.
6x=9
Tāpirihia te -1 ki te 10, ka 9.
x=\frac{9}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{3}{2}
Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
