Whakaoti i te 75%x-5=2.5

$$75 \% x - 5 = 2.5$$

Whakaoti mō x

$$x=10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{75}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{3}{4}x-5=2.5$$

Me tāpiri te 5 ki ngā taha e rua.

$$\frac{3}{4}x=2.5+5$$

Tāpirihia te 2.5 ki te 5, ka 7.5.

$$\frac{3}{4}x=7.5$$

Me whakarea ngā taha e rua ki te \frac{4}{3}, te tau utu o \frac{3}{4}.

$$x=7.5\times \frac{4}{3}$$

Me tahuri ki tau ā-ira 7.5 ki te hautau \frac{75}{10}. Whakahekea te hautanga \frac{75}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{15}{2}\times \frac{4}{3}$$

Me whakarea te \frac{15}{2} ki te \frac{4}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{15\times 4}{2\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{15\times 4}{2\times 3}.

$$x=\frac{60}{6}$$

Whakawehea te 60 ki te 6, kia riro ko 10.

$$x=10$$
