4x-2x-\left(-1\right)=-\left(-2+15x\right)
Hei kimi i te tauaro o 2x-1, kimihia te tauaro o ia taurangi.
4x-2x+1=-\left(-2+15x\right)
Ko te tauaro o -1 ko 1.
2x+1=-\left(-2+15x\right)
Pahekotia te 4x me -2x, ka 2x.
2x+1=-\left(-2\right)-15x
Hei kimi i te tauaro o -2+15x, kimihia te tauaro o ia taurangi.
2x+1=2-15x
Ko te tauaro o -2 ko 2.
2x+1+15x=2
Me tāpiri te 15x ki ngā taha e rua.
17x+1=2
Pahekotia te 2x me 15x, ka 17x.
17x=2-1
Tangohia te 1 mai i ngā taha e rua.
17x=1
Tangohia te 1 i te 2, ka 1.
x=\frac{1}{17}
Whakawehea ngā taha e rua ki te 17.
