Kua tāruatia ki te papatopenga
25k=18\times 5+18k\left(-1\right)
Tē taea kia ōrite te tāupe k ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 18k, arā, te tauraro pātahi he tino iti rawa te kitea o 18,k.
25k=90+18k\left(-1\right)
Whakareatia te 18 ki te 5, ka 90.
25k=90-18k
Whakareatia te 18 ki te -1, ka -18.
25k+18k=90
Me tāpiri te 18k ki ngā taha e rua.
43k=90
Pahekotia te 25k me 18k, ka 43k.
k=\frac{90}{43}
Whakawehea ngā taha e rua ki te 43.
