Whakaoti i te 5.2(w-1)+4=4(w+1)

$$5.2 ( w - 1 ) + 4 = 4 ( w + 1 )$$

Whakaoti mō w

$$w = \frac{13}{3} = 4\frac{1}{3} \approx 4.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 5.2 ki te w-1.

$$5.2w-5.2+4=4\left(w+1\right)$$

Tāpirihia te -5.2 ki te 4, ka -1.2.

$$5.2w-1.2=4\left(w+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te w+1.

$$5.2w-1.2=4w+4$$

Tangohia te 4w mai i ngā taha e rua.

$$5.2w-1.2-4w=4$$

Pahekotia te 5.2w me -4w, ka 1.2w.

$$1.2w-1.2=4$$

Me tāpiri te 1.2 ki ngā taha e rua.

$$1.2w=4+1.2$$

Tāpirihia te 4 ki te 1.2, ka 5.2.

$$1.2w=5.2$$

Whakawehea ngā taha e rua ki te 1.2.

$$w=\frac{5.2}{1.2}$$

Whakarohaina te \frac{5.2}{1.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$w=\frac{52}{12}$$

Whakahekea te hautanga \frac{52}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$w=\frac{13}{3}$$
