Whakaoti i te 2.5(x+40%)=11

$$2.5(x+40 \% )=11$$

Whakaoti mō x

$$x=4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 2.5.

$$x+\frac{40}{100}=\frac{11}{2.5}$$

Whakarohaina te \frac{11}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x+\frac{40}{100}=\frac{110}{25}$$

Whakahekea te hautanga \frac{110}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x+\frac{40}{100}=\frac{22}{5}$$

Whakahekea te hautanga \frac{40}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$x+\frac{2}{5}=\frac{22}{5}$$

Tangohia te \frac{2}{5} mai i ngā taha e rua.

$$x=\frac{22}{5}-\frac{2}{5}$$

Tā te mea he rite te tauraro o \frac{22}{5} me \frac{2}{5}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{22-2}{5}$$

Tangohia te 2 i te 22, ka 20.

$$x=\frac{20}{5}$$

Whakawehea te 20 ki te 5, kia riro ko 4.

$$x=4$$
