-9-x=15+x
Tangohia te 13 i te 4, ka -9.
-9-x-x=15
Tangohia te x mai i ngā taha e rua.
-9-2x=15
Pahekotia te -x me -x, ka -2x.
-2x=15+9
Me tāpiri te 9 ki ngā taha e rua.
-2x=24
Tāpirihia te 15 ki te 9, ka 24.
x=\frac{24}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-12
Whakawehea te 24 ki te -2, kia riro ko -12.
