Whakaoti i te 1000/x1.2=1600/x+3

$$\frac{ 1000 }{ x } 1.2 = \frac{ 1600 }{ x+3 }$$

Whakaoti mō x

$$x=9$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -3,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x,x+3.

$$\left(x+3\right)\times 1000\times 1.2=x\times 1600$$

Whakareatia te 1000 ki te 1.2, ka 1200.

$$\left(x+3\right)\times 1200=x\times 1600$$

Whakamahia te āhuatanga tohatoha hei whakarea te x+3 ki te 1200.

$$1200x+3600=x\times 1600$$

Tangohia te x\times 1600 mai i ngā taha e rua.

$$1200x+3600-x\times 1600=0$$

Pahekotia te 1200x me -x\times 1600, ka -400x.

$$-400x+3600=0$$

Tangohia te 3600 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-400x=-3600$$

Whakawehea ngā taha e rua ki te -400.

$$x=\frac{-3600}{-400}$$

Whakawehea te -3600 ki te -400, kia riro ko 9.

$$x=9$$
