Whakaoti i te 0.06x+0.4(x-2000)=190

$$0.06 x + 0.4 ( x - 2000 ) = 190$$

Whakaoti mō x

$$x = \frac{49500}{23} = 2152\frac{4}{23} \approx 2152.173913043$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.4 ki te x-2000.

$$0.06x+0.4x-800=190$$

Pahekotia te 0.06x me 0.4x, ka 0.46x.

$$0.46x-800=190$$

Me tāpiri te 800 ki ngā taha e rua.

$$0.46x=190+800$$

Tāpirihia te 190 ki te 800, ka 990.

$$0.46x=990$$

Whakawehea ngā taha e rua ki te 0.46.

$$x=\frac{990}{0.46}$$

Whakarohaina te \frac{990}{0.46} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{99000}{46}$$

Whakahekea te hautanga \frac{99000}{46} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{49500}{23}$$
