Whakaoti i te (x-8*2)*15=x-6*2

$$(x-8 \times 2) \times 15=x-6 \times 2$$

Whakaoti mō x

$$x = \frac{114}{7} = 16\frac{2}{7} \approx 16.285714286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 8 ki te 2, ka 16.

$$\left(x-16\right)\times 15=x-6\times 2$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-16 ki te 15.

$$15x-240=x-6\times 2$$

Whakareatia te 6 ki te 2, ka 12.

$$15x-240=x-12$$

Tangohia te x mai i ngā taha e rua.

$$15x-240-x=-12$$

Pahekotia te 15x me -x, ka 14x.

$$14x-240=-12$$

Me tāpiri te 240 ki ngā taha e rua.

$$14x=-12+240$$

Tāpirihia te -12 ki te 240, ka 228.

$$14x=228$$

Whakawehea ngā taha e rua ki te 14.

$$x=\frac{228}{14}$$

Whakahekea te hautanga \frac{228}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{114}{7}$$
