2x+60=124C
Pahekotia te x me x, ka 2x.
124C=2x+60
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{124C}{124}=\frac{2x+60}{124}
Whakawehea ngā taha e rua ki te 124.
C=\frac{2x+60}{124}
Mā te whakawehe ki te 124 ka wetekia te whakareanga ki te 124.
C=\frac{x}{62}+\frac{15}{31}
Whakawehe 60+2x ki te 124.
2x+60=124C
Pahekotia te x me x, ka 2x.
2x=124C-60
Tangohia te 60 mai i ngā taha e rua.
\frac{2x}{2}=\frac{124C-60}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{124C-60}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=62C-30
Whakawehe 124C-60 ki te 2.
