3x+23=-18-2x-24
Pahekotia te x me 2x, ka 3x.
3x+23=-42-2x
Tangohia te 24 i te -18, ka -42.
3x+23+2x=-42
Me tāpiri te 2x ki ngā taha e rua.
5x+23=-42
Pahekotia te 3x me 2x, ka 5x.
5x=-42-23
Tangohia te 23 mai i ngā taha e rua.
5x=-65
Tangohia te 23 i te -42, ka -65.
x=\frac{-65}{5}
Whakawehea ngā taha e rua ki te 5.
x=-13
Whakawehea te -65 ki te 5, kia riro ko -13.
