Kua tāruatia ki te papatopenga
7\times 4=8x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 7x, arā, te tauraro pātahi he tino iti rawa te kitea o x,7.
28=8x
Whakareatia te 7 ki te 4, ka 28.
8x=28
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{28}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{7}{2}
Whakahekea te hautanga \frac{28}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
