-210x-3-4x=23
Tangohia te 4x mai i ngā taha e rua.
-214x-3=23
Pahekotia te -210x me -4x, ka -214x.
-214x=23+3
Me tāpiri te 3 ki ngā taha e rua.
-214x=26
Tāpirihia te 23 ki te 3, ka 26.
x=\frac{26}{-214}
Whakawehea ngā taha e rua ki te -214.
x=-\frac{13}{107}
Whakahekea te hautanga \frac{26}{-214} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
