Kua tāruatia ki te papatopenga
11-5x+x=25
Me tāpiri te x ki ngā taha e rua.
11-4x=25
Pahekotia te -5x me x, ka -4x.
-4x=25-11
Tangohia te 11 mai i ngā taha e rua.
-4x=14
Tangohia te 11 i te 25, ka 14.
x=\frac{14}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-\frac{7}{2}
Whakahekea te hautanga \frac{14}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
