Whakaoti i te 6(w-4)+8w=2(w+9)

$$6 ( w - 4 ) + 8 w = 2 ( w + 9 )$$

Whakaoti mō w

$$w = \frac{7}{2} = 3\frac{1}{2} = 3.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te w-4.

$$6w-24+8w=2\left(w+9\right)$$

Pahekotia te 6w me 8w, ka 14w.

$$14w-24=2\left(w+9\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te w+9.

$$14w-24=2w+18$$

Tangohia te 2w mai i ngā taha e rua.

$$14w-24-2w=18$$

Pahekotia te 14w me -2w, ka 12w.

$$12w-24=18$$

Me tāpiri te 24 ki ngā taha e rua.

$$12w=18+24$$

Tāpirihia te 18 ki te 24, ka 42.

$$12w=42$$

Whakawehea ngā taha e rua ki te 12.

$$w=\frac{42}{12}$$

Whakahekea te hautanga \frac{42}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$w=\frac{7}{2}$$
