Whakaoti i te 0.3x+0.3*0.2*9.8=4

$$0.3 x + 0.3 \times 0.2 \times 9.8 = 4$$

Whakaoti mō x

$$x = \frac{853}{75} = 11\frac{28}{75} \approx 11.373333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0.3 ki te 0.2, ka 0.06.

$$0.3x+0.06\times 9.8=4$$

Whakareatia te 0.06 ki te 9.8, ka 0.588.

$$0.3x+0.588=4$$

Tangohia te 0.588 mai i ngā taha e rua.

$$0.3x=4-0.588$$

Tangohia te 0.588 i te 4, ka 3.412.

$$0.3x=3.412$$

Whakawehea ngā taha e rua ki te 0.3.

$$x=\frac{3.412}{0.3}$$

Whakarohaina te \frac{3.412}{0.3} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{3412}{300}$$

Whakahekea te hautanga \frac{3412}{300} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{853}{75}$$
