Kua tāruatia ki te papatopenga
x-8=5x+10
Pahekotia te 5x me -4x, ka x.
x-8-5x=10
Tangohia te 5x mai i ngā taha e rua.
-4x-8=10
Pahekotia te x me -5x, ka -4x.
-4x=10+8
Me tāpiri te 8 ki ngā taha e rua.
-4x=18
Tāpirihia te 10 ki te 8, ka 18.
x=\frac{18}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-\frac{9}{2}
Whakahekea te hautanga \frac{18}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
