Kua tāruatia ki te papatopenga
2-14x+1=-13x+18+9x
Pahekotia te 5x me -19x, ka -14x.
3-14x=-13x+18+9x
Tāpirihia te 2 ki te 1, ka 3.
3-14x=-4x+18
Pahekotia te -13x me 9x, ka -4x.
3-14x+4x=18
Me tāpiri te 4x ki ngā taha e rua.
3-10x=18
Pahekotia te -14x me 4x, ka -10x.
-10x=18-3
Tangohia te 3 mai i ngā taha e rua.
-10x=15
Tangohia te 3 i te 18, ka 15.
x=\frac{15}{-10}
Whakawehea ngā taha e rua ki te -10.
x=-\frac{3}{2}
Whakahekea te hautanga \frac{15}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
