Whakaoti i te 0.2/40+2x=0.376/2left(108+xright)

$$\frac{ 0.2 }{ 40+2x } = \frac{ 0.376 }{ 2 \left( 108+x \right) }$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -108,-20 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x+20\right)\left(x+108\right), arā, te tauraro pātahi he tino iti rawa te kitea o 40+2x,2\left(108+x\right).

$$\left(x+108\right)\times 0.2=\left(x+20\right)\times 0.376$$

Whakamahia te āhuatanga tohatoha hei whakarea te x+108 ki te 0.2.

$$0.2x+21.6=\left(x+20\right)\times 0.376$$

Whakamahia te āhuatanga tohatoha hei whakarea te x+20 ki te 0.376.

$$0.2x+21.6=0.376x+7.52$$

Tangohia te 0.376x mai i ngā taha e rua.

$$0.2x+21.6-0.376x=7.52$$

Pahekotia te 0.2x me -0.376x, ka -0.176x.

$$-0.176x+21.6=7.52$$

Tangohia te 21.6 mai i ngā taha e rua.

$$-0.176x=7.52-21.6$$

Tangohia te 21.6 i te 7.52, ka -14.08.

$$-0.176x=-14.08$$

Whakawehea ngā taha e rua ki te -0.176.

$$x=\frac{-14.08}{-0.176}$$

Whakarohaina te \frac{-14.08}{-0.176} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{-14080}{-176}$$

Whakawehea te -14080 ki te -176, kia riro ko 80.

$$x=80$$
