Whakaoti i te x+2/4=3(x+8)

$$\frac { x + 2 } { 4 } = 3 ( x + 8 )$$

Whakaoti mō x

$$x = -\frac{94}{11} = -8\frac{6}{11} \approx -8.545454545$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 4.

$$x+2=12\left(x+8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te x+8.

$$x+2=12x+96$$

Tangohia te 12x mai i ngā taha e rua.

$$x+2-12x=96$$

Pahekotia te x me -12x, ka -11x.

$$-11x+2=96$$

Tangohia te 2 mai i ngā taha e rua.

$$-11x=96-2$$

Tangohia te 2 i te 96, ka 94.

$$-11x=94$$

Whakawehea ngā taha e rua ki te -11.

$$x=\frac{94}{-11}$$

Ka taea te hautanga \frac{94}{-11} te tuhi anō ko -\frac{94}{11} mā te tango i te tohu tōraro.

$$x=-\frac{94}{11}$$
