Whakaoti i te 2/3w+4/6=2/3+4/3w

$$\frac { 2 } { 3 } w + \frac { 4 } { 6 } = \frac { 2 } { 3 } + \frac { 4 } { 3 } w$$

Whakaoti mō w

$$w=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{4}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{2}{3}w+\frac{2}{3}=\frac{2}{3}+\frac{4}{3}w$$

Tangohia te \frac{4}{3}w mai i ngā taha e rua.

$$\frac{2}{3}w+\frac{2}{3}-\frac{4}{3}w=\frac{2}{3}$$

Pahekotia te \frac{2}{3}w me -\frac{4}{3}w, ka -\frac{2}{3}w.

$$-\frac{2}{3}w+\frac{2}{3}=\frac{2}{3}$$

Tangohia te \frac{2}{3} mai i ngā taha e rua.

$$-\frac{2}{3}w=\frac{2}{3}-\frac{2}{3}$$

Tangohia te \frac{2}{3} i te \frac{2}{3}, ka 0.

$$-\frac{2}{3}w=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -\frac{2}{3} e ōrite ki 0, me ōrite pū te w ki 0.

$$w=0$$
