Whakaoti i te 1540/310+120x-35000=0

$$\frac{ 1540 }{ 3 } 10+120x-35000=0$$

Whakaoti mō x

$$x = \frac{2240}{9} = 248\frac{8}{9} \approx 248.888888889$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te \frac{1540}{3}\times 10 hei hautanga kotahi.

$$\frac{1540\times 10}{3}+120x-35000=0$$

Whakareatia te 1540 ki te 10, ka 15400.

$$\frac{15400}{3}+120x-35000=0$$

Me tahuri te 35000 ki te hautau \frac{105000}{3}.

$$\frac{15400}{3}+120x-\frac{105000}{3}=0$$

Tā te mea he rite te tauraro o \frac{15400}{3} me \frac{105000}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15400-105000}{3}+120x=0$$

Tangohia te 105000 i te 15400, ka -89600.

$$-\frac{89600}{3}+120x=0$$

Me tāpiri te \frac{89600}{3} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$120x=\frac{89600}{3}$$

Whakawehea ngā taha e rua ki te 120.

$$x=\frac{\frac{89600}{3}}{120}$$

Tuhia te \frac{\frac{89600}{3}}{120} hei hautanga kotahi.

$$x=\frac{89600}{3\times 120}$$

Whakareatia te 3 ki te 120, ka 360.

$$x=\frac{89600}{360}$$

Whakahekea te hautanga \frac{89600}{360} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.

$$x=\frac{2240}{9}$$
