Whakaoti i te 9-(2x+3)=3*(x+8)

$$9-(2x+3)=3 \times (x+8)$$

Whakaoti mō x

$$x = -\frac{18}{5} = -3\frac{3}{5} = -3.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o 2x+3, kimihia te tauaro o ia taurangi.

$$9-2x-3=3\left(x+8\right)$$

Tangohia te 3 i te 9, ka 6.

$$6-2x=3\left(x+8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+8.

$$6-2x=3x+24$$

Tangohia te 3x mai i ngā taha e rua.

$$6-2x-3x=24$$

Pahekotia te -2x me -3x, ka -5x.

$$6-5x=24$$

Tangohia te 6 mai i ngā taha e rua.

$$-5x=24-6$$

Tangohia te 6 i te 24, ka 18.

$$-5x=18$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{18}{-5}$$

Ka taea te hautanga \frac{18}{-5} te tuhi anō ko -\frac{18}{5} mā te tango i te tohu tōraro.

$$x=-\frac{18}{5}$$
