100=32x-12x+60
Whakamahia te āhuatanga tohatoha hei whakarea te -12 ki te x-5.
100=20x+60
Pahekotia te 32x me -12x, ka 20x.
20x+60=100
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
20x=100-60
Tangohia te 60 mai i ngā taha e rua.
20x=40
Tangohia te 60 i te 100, ka 40.
x=\frac{40}{20}
Whakawehea ngā taha e rua ki te 20.
x=2
Whakawehea te 40 ki te 20, kia riro ko 2.
