4x-2x-2+6=24
Hei kimi i te tauaro o 2x+2, kimihia te tauaro o ia taurangi.
2x-2+6=24
Pahekotia te 4x me -2x, ka 2x.
2x+4=24
Tāpirihia te -2 ki te 6, ka 4.
2x=24-4
Tangohia te 4 mai i ngā taha e rua.
2x=20
Tangohia te 4 i te 24, ka 20.
x=\frac{20}{2}
Whakawehea ngā taha e rua ki te 2.
x=10
Whakawehea te 20 ki te 2, kia riro ko 10.
