Kua tāruatia ki te papatopenga
6x\times \frac{2}{3}-6=3\times 5
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 6x, arā, te tauraro pātahi he tino iti rawa te kitea o 3,x,2x.
4x-6=3\times 5
Whakareatia te 6 ki te \frac{2}{3}, ka 4.
4x-6=15
Whakareatia te 3 ki te 5, ka 15.
4x=15+6
Me tāpiri te 6 ki ngā taha e rua.
4x=21
Tāpirihia te 15 ki te 6, ka 21.
x=\frac{21}{4}
Whakawehea ngā taha e rua ki te 4.
