Whakaoti i te 2.6(0.4x-1.4)=-3.9(1.2x-0.9)

$$2.6(0.4x-1.4)=-3.9(1.2x-0.9)$$

Whakaoti mō x

$$x=1.25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2.6 ki te 0.4x-1.4.

$$1.04x-3.64=-3.9\left(1.2x-0.9\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3.9 ki te 1.2x-0.9.

$$1.04x-3.64=-4.68x+3.51$$

Me tāpiri te 4.68x ki ngā taha e rua.

$$1.04x-3.64+4.68x=3.51$$

Pahekotia te 1.04x me 4.68x, ka 5.72x.

$$5.72x-3.64=3.51$$

Me tāpiri te 3.64 ki ngā taha e rua.

$$5.72x=3.51+3.64$$

Tāpirihia te 3.51 ki te 3.64, ka 7.15.

$$5.72x=7.15$$

Whakawehea ngā taha e rua ki te 5.72.

$$x=\frac{7.15}{5.72}$$

Whakarohaina te \frac{7.15}{5.72} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{715}{572}$$

Whakahekea te hautanga \frac{715}{572} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 143.

$$x=\frac{5}{4}$$
