\frac{154}{2}=2x+2+x
Whakawehea ngā taha e rua ki te 2.
77=2x+2+x
Whakawehea te 154 ki te 2, kia riro ko 77.
77=3x+2
Pahekotia te 2x me x, ka 3x.
3x+2=77
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=77-2
Tangohia te 2 mai i ngā taha e rua.
3x=75
Tangohia te 2 i te 77, ka 75.
x=\frac{75}{3}
Whakawehea ngā taha e rua ki te 3.
x=25
Whakawehea te 75 ki te 3, kia riro ko 25.
