Whakaoti i te (7*7-6*6+x)-24div3-2*10=81div9

$$(7 \times 7-6 \times 6+x)-24 \div 3-2 \times 10=81 \div 9$$

Whakaoti mō x

$$x=24$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 7 ki te 7, ka 49.

$$49-6\times 6+x-\frac{24}{3}-2\times 10=\frac{81}{9}$$

Whakareatia te 6 ki te 6, ka 36.

$$49-36+x-\frac{24}{3}-2\times 10=\frac{81}{9}$$

Tangohia te 36 i te 49, ka 13.

$$13+x-\frac{24}{3}-2\times 10=\frac{81}{9}$$

Whakawehea te 24 ki te 3, kia riro ko 8.

$$13+x-8-2\times 10=\frac{81}{9}$$

Tangohia te 8 i te 13, ka 5.

$$5+x-2\times 10=\frac{81}{9}$$

Whakareatia te 2 ki te 10, ka 20.

$$5+x-20=\frac{81}{9}$$

Tangohia te 20 i te 5, ka -15.

$$-15+x=\frac{81}{9}$$

Whakawehea te 81 ki te 9, kia riro ko 9.

$$-15+x=9$$

Me tāpiri te 15 ki ngā taha e rua.

$$x=9+15$$

Tāpirihia te 9 ki te 15, ka 24.

$$x=24$$
