Kua tāruatia ki te papatopenga
15x=x+8
Tē taea kia ōrite te tāupe x ki -8 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 15\left(x+8\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+8,15.
15x-x=8
Tangohia te x mai i ngā taha e rua.
14x=8
Pahekotia te 15x me -x, ka 14x.
x=\frac{8}{14}
Whakawehea ngā taha e rua ki te 14.
x=\frac{4}{7}
Whakahekea te hautanga \frac{8}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
