\frac{1230}{6}=25-x
Whakawehea ngā taha e rua ki te 6.
205=25-x
Whakawehea te 1230 ki te 6, kia riro ko 205.
25-x=205
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=205-25
Tangohia te 25 mai i ngā taha e rua.
-x=180
Tangohia te 25 i te 205, ka 180.
x=-180
Me whakarea ngā taha e rua ki te -1.
