Whakaoti i te 1345+5x/27+x=3.6

$$\frac{ 1345+5x }{ 27+x } =3.6$$

Whakaoti mō x

$$x = -\frac{6239}{7} = -891\frac{2}{7} \approx -891.285714286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -27 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+27.

$$1345+5x=3.6\left(x+27\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3.6 ki te x+27.

$$1345+5x=3.6x+97.2$$

Tangohia te 3.6x mai i ngā taha e rua.

$$1345+5x-3.6x=97.2$$

Pahekotia te 5x me -3.6x, ka 1.4x.

$$1345+1.4x=97.2$$

Tangohia te 1345 mai i ngā taha e rua.

$$1.4x=97.2-1345$$

Tangohia te 1345 i te 97.2, ka -1247.8.

$$1.4x=-1247.8$$

Whakawehea ngā taha e rua ki te 1.4.

$$x=\frac{-1247.8}{1.4}$$

Whakarohaina te \frac{-1247.8}{1.4} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{-12478}{14}$$

Whakahekea te hautanga \frac{-12478}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{6239}{7}$$
