-28=-3x+32
Tāpirihia te -64 ki te 36, ka -28.
-3x+32=-28
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=-28-32
Tangohia te 32 mai i ngā taha e rua.
-3x=-60
Tangohia te 32 i te -28, ka -60.
x=\frac{-60}{-3}
Whakawehea ngā taha e rua ki te -3.
x=20
Whakawehea te -60 ki te -3, kia riro ko 20.
