Kua tāruatia ki te papatopenga
8=3x-\left(1\times 3+1\right)
Whakareatia ngā taha e rua o te whārite ki te 3.
8=3x-\left(3+1\right)
Whakareatia te 1 ki te 3, ka 3.
8=3x-4
Tāpirihia te 3 ki te 1, ka 4.
3x-4=8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=8+4
Me tāpiri te 4 ki ngā taha e rua.
3x=12
Tāpirihia te 8 ki te 4, ka 12.
x=\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
x=4
Whakawehea te 12 ki te 3, kia riro ko 4.
