Whakaoti i te 80%x-50%x=93

$$80 \% x - 50 \% x = 93$$

Whakaoti mō x

$$x=310$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{80}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$\frac{4}{5}x-\frac{50}{100}x=93$$

Whakahekea te hautanga \frac{50}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 50.

$$\frac{4}{5}x-\frac{1}{2}x=93$$

Pahekotia te \frac{4}{5}x me -\frac{1}{2}x, ka \frac{3}{10}x.

$$\frac{3}{10}x=93$$

Me whakarea ngā taha e rua ki te \frac{10}{3}, te tau utu o \frac{3}{10}.

$$x=93\times \frac{10}{3}$$

Tuhia te 93\times \frac{10}{3} hei hautanga kotahi.

$$x=\frac{93\times 10}{3}$$

Whakareatia te 93 ki te 10, ka 930.

$$x=\frac{930}{3}$$

Whakawehea te 930 ki te 3, kia riro ko 310.

$$x=310$$
