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