Kua tāruatia ki te papatopenga
10x-5-2\times 2x=10
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-1.
10x-5-4x=10
Whakareatia te 2 ki te 2, ka 4.
6x-5=10
Pahekotia te 10x me -4x, ka 6x.
6x=10+5
Me tāpiri te 5 ki ngā taha e rua.
6x=15
Tāpirihia te 10 ki te 5, ka 15.
x=\frac{15}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{5}{2}
Whakahekea te hautanga \frac{15}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
