Whakaoti i te 5*068+09x/5+x=075

$$\frac{ 5 \cdot 068+09x }{ 5+x } =075$$

Whakaoti mō x

$$x\neq -5$$

Ngā Upane Otinga

Tē taea kia ōrite te tāupe x ki -5 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+5.

$$5\times 0\times 68+0\times 9x=0\times 75\left(x+5\right)$$

Mahia ngā whakarea.

$$0\times 68+0x=0\times 75\left(x+5\right)$$

Whakareatia te 0 ki te 68, ka 0.

$$0+0x=0\times 75\left(x+5\right)$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0+0=0\times 75\left(x+5\right)$$

Tāpirihia te 0 ki te 0, ka 0.

$$0=0\times 75\left(x+5\right)$$

Whakareatia te 0 ki te 75, ka 0.

$$0=0\left(x+5\right)$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=0$$

Whakatauritea te 0 me te 0.

$$\text{true}$$

He pono tēnei mō tētahi x ahakoa.

$$x\in \mathrm{R}$$

Tē taea kia ōrite te tāupe x ki -5.

$$x\in \mathrm{R}\setminus -5$$
