Kua tāruatia ki te papatopenga
1-10-10x=15
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 5+5x.
-9-10x=15
Tangohia te 10 i te 1, ka -9.
-10x=15+9
Me tāpiri te 9 ki ngā taha e rua.
-10x=24
Tāpirihia te 15 ki te 9, ka 24.
x=\frac{24}{-10}
Whakawehea ngā taha e rua ki te -10.
x=-\frac{12}{5}
Whakahekea te hautanga \frac{24}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
