3x-9=3x-5x-\left(x+3\right)
Pahekotia te 8x me -5x, ka 3x.
3x-9=-2x-\left(x+3\right)
Pahekotia te 3x me -5x, ka -2x.
3x-9=-2x-x-3
Hei kimi i te tauaro o x+3, kimihia te tauaro o ia taurangi.
3x-9=-3x-3
Pahekotia te -2x me -x, ka -3x.
3x-9+3x=-3
Me tāpiri te 3x ki ngā taha e rua.
6x-9=-3
Pahekotia te 3x me 3x, ka 6x.
6x=-3+9
Me tāpiri te 9 ki ngā taha e rua.
6x=6
Tāpirihia te -3 ki te 9, ka 6.
x=\frac{6}{6}
Whakawehea ngā taha e rua ki te 6.
x=1
Whakawehea te 6 ki te 6, kia riro ko 1.
