Tohaina
Kua tāruatia ki te papatopenga
w\left(15+6\right)=2100\times 1.2\times 9
Tē taea kia ōrite te tāupe w ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2100w, arā, te tauraro pātahi he tino iti rawa te kitea o 2100,w.
w\times 21=2100\times 1.2\times 9
Tāpirihia te 15 ki te 6, ka 21.
w\times 21=2520\times 9
Whakareatia te 2100 ki te 1.2, ka 2520.
w\times 21=22680
Whakareatia te 2520 ki te 9, ka 22680.
w=\frac{22680}{21}
Whakawehea ngā taha e rua ki te 21.
w=1080
Whakawehea te 22680 ki te 21, kia riro ko 1080.
