18=3\left(x-3\right)
Tangohia te 14 i te 32, ka 18.
18=3x-9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
3x-9=18
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=18+9
Me tāpiri te 9 ki ngā taha e rua.
3x=27
Tāpirihia te 18 ki te 9, ka 27.
x=\frac{27}{3}
Whakawehea ngā taha e rua ki te 3.
x=9
Whakawehea te 27 ki te 3, kia riro ko 9.
