4x-2x-\left(-11\right)=25
Hei kimi i te tauaro o 2x-11, kimihia te tauaro o ia taurangi.
4x-2x+11=25
Ko te tauaro o -11 ko 11.
2x+11=25
Pahekotia te 4x me -2x, ka 2x.
2x=25-11
Tangohia te 11 mai i ngā taha e rua.
2x=14
Tangohia te 11 i te 25, ka 14.
x=\frac{14}{2}
Whakawehea ngā taha e rua ki te 2.
x=7
Whakawehea te 14 ki te 2, kia riro ko 7.
