Whakaoti i te 100*100+15x=60*(100+x)

$$100 \times 100 + 15 x = 60 \times ( 100 + x )$$

Whakaoti mō x

$$x = \frac{800}{9} = 88\frac{8}{9} \approx 88.888888889$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 100 ki te 100, ka 10000.

$$10000+15x=60\left(100+x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 60 ki te 100+x.

$$10000+15x=6000+60x$$

Tangohia te 60x mai i ngā taha e rua.

$$10000+15x-60x=6000$$

Pahekotia te 15x me -60x, ka -45x.

$$10000-45x=6000$$

Tangohia te 10000 mai i ngā taha e rua.

$$-45x=6000-10000$$

Tangohia te 10000 i te 6000, ka -4000.

$$-45x=-4000$$

Whakawehea ngā taha e rua ki te -45.

$$x=\frac{-4000}{-45}$$

Whakahekea te hautanga \frac{-4000}{-45} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -5.

$$x=\frac{800}{9}$$
