Whakaoti i te 800(1.6+x)=1000(1+x)

$$800(1.6+x)=1000(1+x)$$

Whakaoti mō x

$$x=1.4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 800 ki te 1.6+x.

$$1280+800x=1000\left(1+x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 1000 ki te 1+x.

$$1280+800x=1000+1000x$$

Tangohia te 1000x mai i ngā taha e rua.

$$1280+800x-1000x=1000$$

Pahekotia te 800x me -1000x, ka -200x.

$$1280-200x=1000$$

Tangohia te 1280 mai i ngā taha e rua.

$$-200x=1000-1280$$

Tangohia te 1280 i te 1000, ka -280.

$$-200x=-280$$

Whakawehea ngā taha e rua ki te -200.

$$x=\frac{-280}{-200}$$

Whakahekea te hautanga \frac{-280}{-200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -40.

$$x=\frac{7}{5}$$
