Whakaoti i te 65*09-50+50x=65*09*105-50*(1-2x)

$$65 \times 09-50+50x=65 \times 09 \times 105-50 \times (1-2x)$$

Whakaoti mō x

$$x=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 65 ki te 0, ka 0.

$$0\times 9-50+50x=65\times 0\times 9\times 105-50\left(1-2x\right)$$

Whakareatia te 0 ki te 9, ka 0.

$$0-50+50x=65\times 0\times 9\times 105-50\left(1-2x\right)$$

Tangohia te 50 i te 0, ka -50.

$$-50+50x=65\times 0\times 9\times 105-50\left(1-2x\right)$$

Whakareatia te 65 ki te 0, ka 0.

$$-50+50x=0\times 9\times 105-50\left(1-2x\right)$$

Whakareatia te 0 ki te 9, ka 0.

$$-50+50x=0\times 105-50\left(1-2x\right)$$

Whakareatia te 0 ki te 105, ka 0.

$$-50+50x=0-50\left(1-2x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -50 ki te 1-2x.

$$-50+50x=0-50+100x$$

Tangohia te 50 i te 0, ka -50.

$$-50+50x=-50+100x$$

Tangohia te 100x mai i ngā taha e rua.

$$-50+50x-100x=-50$$

Pahekotia te 50x me -100x, ka -50x.

$$-50-50x=-50$$

Me tāpiri te 50 ki ngā taha e rua.

$$-50x=-50+50$$

Tāpirihia te -50 ki te 50, ka 0.

$$-50x=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -50 e ōrite ki 0, me ōrite pū te x ki 0.

$$x=0$$
