36=3x-\left(4-x\right)
Tangohia te 2 i te 38, ka 36.
36=3x-4-\left(-x\right)
Hei kimi i te tauaro o 4-x, kimihia te tauaro o ia taurangi.
36=3x-4+x
Ko te tauaro o -x ko x.
36=4x-4
Pahekotia te 3x me x, ka 4x.
4x-4=36
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=36+4
Me tāpiri te 4 ki ngā taha e rua.
4x=40
Tāpirihia te 36 ki te 4, ka 40.
x=\frac{40}{4}
Whakawehea ngā taha e rua ki te 4.
x=10
Whakawehea te 40 ki te 4, kia riro ko 10.
