Whakaoti i te x-10*5/frac{50{7}}+10=9

$$x-10 \times \frac{ 5 }{ \frac{ 50 }{ 7 } } +10=9$$

Whakaoti mō x

$$x=6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehe 5 ki te \frac{50}{7} mā te whakarea 5 ki te tau huripoki o \frac{50}{7}.

$$x-10\times 5\times \frac{7}{50}+10=9$$

Tuhia te 5\times \frac{7}{50} hei hautanga kotahi.

$$x-10\times \frac{5\times 7}{50}+10=9$$

Whakareatia te 5 ki te 7, ka 35.

$$x-10\times \frac{35}{50}+10=9$$

Whakahekea te hautanga \frac{35}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x-10\times \frac{7}{10}+10=9$$

Me whakakore te 10 me te 10.

$$x-7+10=9$$

Tāpirihia te -7 ki te 10, ka 3.

$$x+3=9$$

Tangohia te 3 mai i ngā taha e rua.

$$x=9-3$$

Tangohia te 3 i te 9, ka 6.

$$x=6$$
