Whakaoti i te 10.25(4a-3)=0.5a-9

$$10.25 ( 4 a - 3 ) = 0.5 a - 9$$

Whakaoti mō a

$$a=\frac{29}{54}\approx 0.537037037$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 10.25 ki te 4a-3.

$$41a-30.75=0.5a-9$$

Tangohia te 0.5a mai i ngā taha e rua.

$$41a-30.75-0.5a=-9$$

Pahekotia te 41a me -0.5a, ka 40.5a.

$$40.5a-30.75=-9$$

Me tāpiri te 30.75 ki ngā taha e rua.

$$40.5a=-9+30.75$$

Tāpirihia te -9 ki te 30.75, ka 21.75.

$$40.5a=21.75$$

Whakawehea ngā taha e rua ki te 40.5.

$$a=\frac{21.75}{40.5}$$

Whakarohaina te \frac{21.75}{40.5} mā te whakarea i te taurunga me te tauraro ki te 100.

$$a=\frac{2175}{4050}$$

Whakahekea te hautanga \frac{2175}{4050} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 75.

$$a=\frac{29}{54}$$
