Whakaoti i te -(x-12)=-4left(3x+5right)

$$-(x-12) = -4 \left( 3x+5 \right)$$

Whakaoti mō x

$$x = -\frac{32}{11} = -2\frac{10}{11} \approx -2.909090909$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o x-12, kimihia te tauaro o ia taurangi.

$$-x-\left(-12\right)=-4\left(3x+5\right)$$

Ko te tauaro o -12 ko 12.

$$-x+12=-4\left(3x+5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 3x+5.

$$-x+12=-12x-20$$

Me tāpiri te 12x ki ngā taha e rua.

$$-x+12+12x=-20$$

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

$$11x+12=-20$$

Tangohia te 12 mai i ngā taha e rua.

$$11x=-20-12$$

Tangohia te 12 i te -20, ka -32.

$$11x=-32$$

Whakawehea ngā taha e rua ki te 11.

$$x=\frac{-32}{11}$$

Ka taea te hautanga \frac{-32}{11} te tuhi anō ko -\frac{32}{11} mā te tango i te tohu tōraro.

$$x=-\frac{32}{11}$$
