Tohaina
Kua tāruatia ki te papatopenga
3n=3+5n\left(-\frac{1}{5}\right)
Tē taea kia ōrite te tāupe n ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 5n, arā, te tauraro pātahi he tino iti rawa te kitea o 5,5n.
3n=3-n
Whakareatia te 5 ki te -\frac{1}{5}, ka -1.
3n+n=3
Me tāpiri te n ki ngā taha e rua.
4n=3
Pahekotia te 3n me n, ka 4n.
n=\frac{3}{4}
Whakawehea ngā taha e rua ki te 4.
